Abstract: Disclosed herein is a method and apparatus for detecting surveillance devices on a telephone line and deployment of countermeasures therefor. The apparatus comprises a line monitoring circuit for evaluating whether the phone is off hook or ringing. A test generation circuit produces a test signal to be injected into a line and issues test commands. A signal response analysis circuit compares a test signal response to a baseline signal response and reports an anomaly when the difference between a test signal response and a baseline signal response exceeds a threshold. Additionally, an anomaly may be reported when an unusual signal is detected, such as a clock. A detection management circuit issues countermeasures to the anomaly based on programmed responses.

Abstract: Disclosed herein is a system and method for a seamless curb system suitable for a sanitary environment while providing an energy absorbing structure. The multicellular structure has a substantially uniform cross section. The structure is formed of hi-density, energy absorbing, expanding polypropylene foam, similar to bumper systems used in cars and trucks. An outer shell is disposed over at least a front portion of the structure. The outer shell may be stainless steel or a polyurea/polyaspartic reinforced coating, as examples. The elements are sealed to each other in an end to end relationship adjacent to a wall to form an energy absorbing protective barrier to the wall. At least one anchor is disposed in a slot in the floor of the manufacturing facility to provide support.

Abstract: An exercise desk that may be attached to a piece of exercise equipment is disclosed that that has an adjustable desk top. By providing an adapter capable of independent adjustment of the desk top, horizontal position of the adapter and vertical position of the adapter, the exercise desk may be mounted to a variety of exercise devices. Furthermore, the desk top is selectively pivotable.

Abstract: A ventilation system and method for venting a cockpit of a power boat is disclosed herein. The ventilation system comprises a windshield extending from a foredeck of the powerboat, a cockpit cover at least covering the cockpit and a frame. A cockpit vent comprises a frame defining at least one aperature for introducing ambient air into the cockpit. The frame is disposed between the windshield and cockpit cover and includes a windshield engagement member and a cover engagement member spaced from the windshield engagement member.

Abstract: Disclosed herein is a sensor assembly (10) for attachment to an electrical conductor (5), which includes a base (20) having a cavity (22) and a pair of detector housings (30) extending from the base (20). The detector housings (30) are laterally spaced and substantially parallel and are provided to receive a magnetic field detector. An electronic circuit card (70) is disposed within the base cavity (22) and is operatively coupled to the magnetic field detectors. Additionally, an auxiliary circuit card (90)) that contains logic for detecting an arc fault may be provided for communicating with the electronic circuit card (70).

Abstract: Electrical equipment (14) is safeguarded from damage due to parallel arc faults by a circuit that provides several levels of protection. A semiconductor switch (18) and a current sensor (24) are placed in series with the electrical equipment (14). When the current to the equipment exceeds a first threshold for a predefined period of time, the semiconductor switch (18) is rendered non-conductive until the circuit is specifically reset. When the current to the equipment exceeds a greater second threshold, a pulsed signal alternately places the semiconductor switch (18) in conductive and non-conductive states so that the average current applied to the equipment (14) is within an acceptable level. The pulses are measured to determine whether a parallel arc fault has occurred. When the measured pulses (74) are within a predetermined range, a parallel arc fault is declared and the semiconductor switch (18) is rendered non-conductive.

Abstract: A clutch release mechanism is slideably disposed over a driven shaft to transfer force from a plurality of levers or springs to a pressure plate. The release mechanism is axially displaced to engage or release a clutch. A modular release mechanism disclosed herein comprises a release sleeve which is slideably disposed on a driven shaft, the release sleeve has an axis of rotation, a first end and a second end. The release sleeve has a lever engagement portion disposed at the first end for contact with a release lever. A bearing is disposed about the axis of rotation and has an inward race and an outer race. The release sleeve has a bearing housing portion disposed at the second end for receiving the bearing. The bearing housing portion has a shoulder for locating the bearing therein.

Abstract: A friction clutch comprising an adjustment mechanism that includes a stationary annular cam, a rotating cam, a cam biasing spring, a fulcrum ring, a wear sensor and an adjustment limiting device. The stationary annular cam is centered about an axis of rotation and is fixed relative to a pressure plate. The stationary cam has a stationary cam surface with a plurality of ramps thereon. The rotating cam is also centered about an axis of rotation and is rotatable relative to the pressure plate. The rotating cam has a rotating cam surface with a plurality of ramps thereon and is disposed between the adjustment limiting device and the stationary cam. The rotating cam surface is in contact with a stationary cam surface, and rotating cam rotates with respect to the stationary cam to move an axial end of the rotating cam from a first axial position to a second axial position relative to a cover. A cam biasing spring has a first end received in the rotating cam and a second end attached to the pressure plate.

Abstract: In a transmission inertia brake a ball ramp mechanism is used to load a clutch pack to slow a rotating transmission shaft where the clutch pack is carried on a one piece drive assembly having a gear section for meshing with a transmission gear, an extension section for engaging a thrust plate in an isolator assembly, a clutch section for engaging plurality of driven clutch plates in the clutch pack and a bearing section for rotational support within a brake housing. An armature having an angled peripheral surface engages a mating friction surface formed in an end plate to form a core clutch, the armature being magnetically pulled upon energization of an electrical coil. The armature is nonrotatably connected to the control ring of the ball ramp mechanism through at least one connecting pin. Belleville washers are used to apply an axial load on the ball ramp mechanism. A gerotor oil pump provides a cooling lubricant through the clutch pack in the ball ramp mechanism.
