Abstract:
An electrical probe is provided for use with an electrical instrument, such as an oscilloscope. The probe includes a probe body, a sensing element affixed to the probe body for sensing an electrical parameter and a storage device containing probe information that uniquely identifies the probe. The probe information is electronically transferred from the storage device to the electrical instrument when the probe is connected to the electrical instrument. The electrical instrument stores calibration information that is associated with the probe. The electrical instrument uses the probe information received from the storage device in the probe to access the associated calibration information. The accessed calibration information is used to calibrate measurements made with the probe.

A high efficiency non-dissipative snubber circuit suitable for most power supplies used in international markets is disclosed. Circuit uses diode-capacitor-inductor structure to capture input voltage equivalent and reverse polarity on snubber capacitor. No external voltage source is required.
Abstract:
A mass-producible, cost-effective discrete electrical protection device utilizing a precision gap between two electrically conductive members attached to an electrically insulating substrate to provide over-voltage protection to an electrical device. In one aspect, the electrical protection device is a surface mountable device. In another aspect, the device has through-holes for accommodating leads on an electrical connector. Methods are provided also for making the electrical protection device.
Abstract:
A power supply includes a voltage regulator for generating a regulated voltage in response to an input voltage and an error signal, first and second output terminals connected to the voltage regulator for coupling the power supply to a load, first and second sense terminals and a sensing circuit for generating the error signal. The sensing circuit includes a high input impedance differential amplifier having first and second inputs respectively coupled to the first and second sense terminals for measuring a sense voltage between the sense terminals. The power supply may be operated in a remote sensing mode or in a local sensing mode. In the local sensing mode, no connections are required between the sense terminals and the output terminals.
Abstract:
A regulated power supply that provides two desired direct current voltages at respective outputs thereof, the supply maintaining the difference between voltages appearing at the outputs the same as the difference between the desired values, series regulators respectively coupled to each output that are in a saturation mode when a voltage that is a fraction of the voltage between the outputs lies within a given range, where one of the series regulators is placed in a linear mode when the voltage is at or beyond one edge of the range, and the other series regulators is placed in a linear mode when the voltage is at or beyond the other end of the range.
Abstract:
An electrical connection system, such as a Bayonet Niel-Concelman (BNC) connection system, includes two connector assemblies and enables electrical connections between the two connector assemblies to be established and maintained. The two connector assemblies respectively include a first connector and a second connector. One of the connector assemblies includes a contact pin, and the other connector assembly includes a mechanical support having a tapered recess. The first connector interlocks with the second connector, and the contact pin is received by the recess and engages the mechanical support, when the first and second connectors are interlocked. Because the recess is tapered, the contact pin is guided toward the center of the recess as the contact pin is pressed against the surface of the mechanical support exposed by the recess, making it easier to establish and maintain an electrical connection with the contact pin.
Abstract:
A locking assembly for releasably locking together a mating connector pair comprises a housing having a central aperture therethrough and adapted to be mounted to the first connector portion of the mating connector pair. A locking sleeve also having a central aperture is sized to receive the first connector portion and is also sized to be slidably received by the central aperture of the housing so that the locking sleeve can be rotated within the housing from a locked position to an unlocked position. The locking sleeve also includes a locking pin engaging boss for releasably engaging a locking pin associated with the second connector portion of the mating connector pair. Specifically, the locking pin engaging boss rotates the locking sleeve to the unlocked position as the first connector portion is engaged with the second connector portion. The locking pin engaging boss also allows the locking sleeve to be rotated to the locked position when the first and second connector portions are fully engaged. A biasing device associated with the locking sleeve biases the locking sleeve to the locked position.

Abstract:
Accordingly, a supplemental electrical connector assembly for transmitting at least one supplemental electrical signal to a supplemental contact pad associated with a mating electrical connector pair may comprise a pin block mounted to a first connector portion of the mating electrical connector pair. A pogo pin assembly having a connector pin positioned at one end and a contact pin positioned at the other end is mounted to the pin block so that the contact pin extends from the front end of the pin block and so that the connector pin extends from the rear end of the pin block. A printed wiring board attached to the first connector portion of the mating electrical connector pair engages the connector pin on the pogo pin assembly.
