Abstract:
A progammable power supply for providing a regulated DC output power is disclosed. The power supply provides the output power to any one of a plurality of electronic devices adapted for receiving the output power at an operational voltage or an operational current. The power supply receives a programming signal to maintain the output power at the operational voltage or operational current associated with a particular selected electronic device. Accordingly, by varying the programming signal, the power supply can be programmed to provide output power to any one of several electronic devices having differing input power requirements.

Abstract:
The present invention is directed to a downhole, high-current, low-impedance, feed-through connector for passing electrical current, preferably high frequency AC current, between a tool compartment having relatively high pressure and another tool compartment having relatively low pressure. The primary intended application of the present invention is to connect a radio frequency transmitter/receiver antenna to the antenna's tuning capacitors, but the present invention is applicable to any downhole application requiring the transmission of high electrical current across a barrier having a high pressure differential. This invention minimizes the force acting on the connector due to the high pressure differential by providing a conductor preferably having either a wave-like cross-section or a multi-finned cross-section, thereby minimizing the overall cross-sectional area of the connector yet providing sufficient cross-sectional area of the conductor to carry the necessary amount of electrical current.
Abstract:
The subject matter disclosed herein relates to mechanisms for programming power supply circuitry for providing an appropriate current or voltage to powering portable devices or recharge batteries. More particularly, a power supply is coupled to a portable device of battery through a connector which is associated with the portable device or battery. The connecter includes resistive circuitry which is detectable at the power supply for programming the power supply to provide the appropriate voltage or current associated with the portable device or battery.
Abstract:
The invention relates to a fitting base (1) of a plug (2) comprising: a supporting element (11) comprising at least one opening suitable for receiving at least one connector of the plug (2), a first stationary portion (12) projecting from the supporting element (11), a first movable portion (13) secured to the first stationary portion (12), said movable portion (13) having a shape and dimensions suitable for the insertion thereof into a first cavity (21) in the plug (2) when the at least one connector of the plug (2) is fitted in the at least one opening in the supporting element (11). The invention also relates to a plug (2) and to a locking system (3).
Abstract:
A wall plate assembly including a wall plate with an integrated USB module. The assembly includes a USB connector and printed circuit board formed together on the wall plate as an integral whole. By placing USB extender circuitry directly on the printed circuit board, rather than in a separate housing, the present assembly can maintain its bus- powered attributes without the bulk of a separate extender housing. A quick-connect coupling enables fast electrical connection and disconnection with a complementary quick-connect coupling on a USB wire.
Abstract:
The present invention discloses a combined apparatus of a Bluetooth earset and a charging dock, characterized in that the combined apparatus comprises the Bluetooth earset and the charging dock which can be connected to a power supply, said charging dock comprising a main body portion, and one end of the charging dock is an electrical connection portion which is connected to a DC power supply, and the other end of the charging dock is a holding cavity portion for fixing the Bluetooth earset, and electric contacts in the holding cavity portion are adapted to electric contacts on a bottom end of the Bluetooth earset.
Abstract:
A secondary adapter for receiving a DC power signal and providing an output power signal as an input to an AC power adapter is disclosed. The AC power adapter may then provide a DC power signal to meet the input power from an AC power source, the secondary adapter converts a DC power source to provide an input power signal which is sufficient to power the AC power adpater converts a DC power source to provide an input power signal which is sufficient to power the AC power adapter. The secondary adapter enables the AC power adapter to provide power to the electronic appliance from either an AC power source of a DC power source.
