摘要： A device for positioning a reciprocating saw blade within a tube stub, such that the device is inserted into the tube stub and dynamically positions the reciprocating saw blade relative to the interior surface of the tube stub so that the saw blade can make a controlled longitudinal cut into the interior of the tube stub to a precise depth.

摘要： A hammer has a claw assembly that is linearly moveable relative to the head of the hammer so as to improve leverage and range of prying for nail removal. A locking mechanism secures the claw assembly in a position. The locking mechanism may be automatic or manual, and may comprise a ratcheting mechanism with a pawl and rack, or a clamping mechanism with a deflectable sleeve and engaged bar, or a biased pin lock mechanism.

摘要： A power supply includes a rectifier circuit having a rectifier mode and a voltage doubler mode. An AC switch is coupled to the rectifier circuit and switches the rectifier circuit into the rectifier mode when a higher AC line voltage is supplied and a voltage doubler mode when a lower AC line voltage is supplied. A control circuit is connected to the AC switch and detects the higher or lower AC line voltages and is operable for latching the rectifier circuit in the rectifier mode when the higher AC line voltage is detected and in the voltage doubler mode when the lower AC line voltage is detected. The latch circuit maintains a latched configuration in either the rectifier or voltage doubler mode during voltage transients and in the rectifier mode during start-up transients.

摘要： A hammer includes a handle, a head assembly affixed to the handle, and a claw assembly slidably disposed on the handle. The handle includes apertures interspaced linearly along the length of the handle. The head assembly includes a throat and a striking face. The claw assembly includes a claw, an annular sleeve slidably disposed around the handle for enabling linear adjustment of the claw assembly along the length of the handle, and a ratcheting lever coupled to the sleeve for adjusting the position of the claw relative to the head assembly during operation. The ratcheting lever includes a spring-biased locking pin for removably engaging any one of the apertures to selectively secure the claw assembly to the handle in a desired position and a depressible release arm for releasing the spring-biased locking pin from the apertures to enable the claw assembly to slide along the length of the handle.

摘要： A method and apparatus detects a ground fault on a span-powered telecommunication wireline within a plurality of span-powered wireline segments, to respective ones of which DSL-Cs are coupled, so that a ground fault may be detected when power is delivered by the DSL-C over a respective wireline segment to a respective downstream functional RT. A respective DSL-C measures a first voltage across a first sense resistor representative of current flowing in a first portion of its wireline segment to the RT, and also measures a second voltage across a second sense resistor representative of current flowing in a second portion of the wireline segment from the RT. In response to a difference in the first and second voltages an output representative of a ground fault in that wireline segment is generated.

摘要： A regulated power supply interface has a current feedback and voltage level shift circuit that monitors power supply output (load) current and controllably diverts current to a current reference node. A differential amplifier-based, voltage feedback and voltage level shift circuit monitors the load voltage and controllably diverts output current to the current reference node. A current mode setpoint circuit has multiple voltage dropping current paths, through one or more of which a summation of the diverted load currents are programmably directed, to generate a control voltage for controlling the operation of a pulse width modulator unit of the regulated power supply.
