Batteriser
The Batteroo Boost (formerly known as the Batteriser ( )) is a line of products designed by Batteroo, Inc. that is claimed to significantly extend battery life by using a miniature boost voltage regulator. It was crowd-funded on Indiegogo. The company is based in Sunnyvale, California and founded by Bob Roohparvar and Frankie Roohparvar. Product details A patent was filed by Fariborz Frankie Roohparvar with the priority date of September 20, 2010. The Batteroo Boost is claimed to extend the life of both new and used batteries. Batteroo has said that Batterisers are non-toxic, reusable, and coated with a non-conductive coating to prevent any risk of shorts. They also claim that a built-in reverse polarity protection mechanism eliminates dangers of inserting a battery into the Batteriser the wrong way. Crowdfunding completed between July 2015 produced $394,459, while the initial goal was $30,000. During the crowdfunding Batteroo announced they would be producing Batteroo Boost f ...

Consumer Electronics
Consumer electronics or home electronics are electronic (analog or digital) equipment intended for everyday use, typically in private homes. Consumer electronics include devices used for entertainment, communications and recreation. Usually referred to as black goods due to many products being housed in black or dark casings. This term is used to distinguish them from "white goods" which are meant for housekeeping tasks, such as washing machines and refrigerators, although nowadays, these would be considered black goods, some of these being connected to the Internet. In British English, they are often called brown goods by producers and sellers. In the 2010s, this distinction is absent in large big box consumer electronics stores, which sell entertainment, communication and home office devices, light fixtures and appliances, including the bathroom type. Radio broadcasting in the early 20th century brought the first major consumer product, the broadcast receiver. Later produc ...

Joule Thief
A joule thief is a minimalist self-oscillating voltage booster that is small, low-cost, and easy to build, typically used for driving small loads. This circuit is also known by other names such as ''blocking oscillator'', ''joule ringer'', or ''vampire torch''. It can use nearly all of the energy in a single-cell electric battery, even far below the voltage where other circuits consider the battery fully discharged (or "dead"); hence the name, which suggests the notion that the circuit is ''stealing'' energy or "joules" from the source – the term is a pun on "jewel thief". The circuit is a variant of the blocking oscillator that forms an unregulated voltage boost converter. The output voltage is increased at the expense of higher current draw on the input, but the integrated (average) current of the output is lowered and brightness of a luminescence decreased. History Prior art The joule thief is not a new concept. Basically, it adds an LED to the output of a self-os ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Undervoltage-lockout
The undervoltage-lockout (UVLO) is an electronic circuit used to turn off the power of an electronic device in the event of the voltage dropping below the operational value that could cause unpredictable system behavior. For instance, in Electric battery, battery powered Embedded system, embedded devices, UVLOs can be used to monitor the battery voltage and turn off the embedded device's circuit if the battery voltage drops below a specific threshold, thus protecting the associated equipment. Some variants may also have unique values for power-up (positive-going) and power-down (negative-going) thresholds. Usages Typical usages include: * Electrical ballast circuits to switch them off in the event of voltage falling below the operational value. * Switched-mode power supply, Switched-mode power supplies. When the system supply output impedance is higher than the input impedance of the voltage regulator, regulator, an UVLO with a higher hysteresis should be used to prevent oscillat ...

IP Address
An Internet Protocol address (IP address) is a numerical label such as that is connected to a computer network that uses the Internet Protocol for communication.. Updated by . An IP address serves two main functions: network interface identification and location addressing. Internet Protocol version 4 (IPv4) defines an IP address as a 32-bit number. However, because of the growth of the Internet and the depletion of available IPv4 addresses, a new version of IP (IPv6), using 128 bits for the IP address, was standardized in 1998. IPv6 deployment has been ongoing since the mid-2000s. IP addresses are written and displayed in human-readable notations, such as in IPv4, and in IPv6. The size of the routing prefix of the address is designated in CIDR notation by suffixing the address with the number of significant bits, e.g., , which is equivalent to the historically used subnet mask . The IP address space is managed globally by the Internet Assigned Numbers Authority (IA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Equivalent Series Resistance
Practical capacitors and inductors as used in electric circuits are not ideal components with only capacitance or inductance. However, they can be treated, to a very good degree of approximation, as being ideal capacitors and inductors in series with a resistance; this resistance is defined as the equivalent series resistance (ESR). If not otherwise specified, the ESR is always an AC resistance, which means it is measured at specified frequencies, 100 kHz for switched-mode power supply components, 120 Hz for linear power-supply components, and at its self-resonant frequency for general-application components. Additionally, audio components may report a " Q factor", incorporating ESR among other things, at 1000 Hz. Overview Electrical circuit theory deals with ideal resistors, capacitors and inductors, each assumed to contribute only resistance, capacitance or inductance to the circuit. However, all components have a non-zero value of each of these parameters. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regulated Power Supply
A regulated power supply is an embedded circuit; it converts unregulated AC (Alternating Current) into a constant DC. With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable voltage (or less often current), to a circuit or device that must be operated within certain power supply limits. The output from the regulated power supply may be alternating or unidirectional, but is nearly always DC (Direct Current). The type of stabilization used may be restricted to ensuring that the output remains within certain limits under various load conditions, or it may also include compensation for variations in its own supply source. The latter is much more common today. Applications D.C. variable bench supply A bench power supply usually refers to a power supply capable of supplying a variety of output voltages useful for BE ( bench testing) electronic circuits, possibly with continuous variation of the output voltage, or just some preset voltages.

David L
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, David ...

Brownout (electricity)
A brownout is a drop in voltage in an electrical power supply system. Unintentional brownouts can be caused by excessive electricity demand, severe weather events, or a malfunction or error affecting electrical grid control or monitoring systems. Intentional brownouts are used for load reduction in an emergency, or to prevent a total grid power outage due to high demand. The term ''brownout'' comes from the dimming of incandescent lighting when voltage reduces. In some countries, the term ''brownout'' refers not to a drop in voltage but to an intentional or unintentional power outage (or blackout). Effects Different types of electrical apparatus will react in different ways to a voltage reduction. Some devices will be severely affected, while others may not be affected at all. Resistive loads The heat output of any resistive device, such as an electric space heater, is equal to the power consumption, which is directly proportional to the square of the applied voltage if ...
