Title: Loopback test starting system
Inventor: OHMORI HISAKAZU
IPC: H04J3/14
Filed: 1990-08-29
Granted: 1994-07-12
Abstract: ABSTRACT OF THE DISCLOSURE           A loopback test starting system is provided for starting a loopback test.  The loopback test starting system includes a first loopback controller which detects a first loopback control signal from a digital data services network side and generates a first loopback starting signal.  In addition, a second loopback controller is provided which detects a second loopback control signal from a subscriber side and generates a second loopback starting signal in response.  The loopback test starting system also includes a first loopback forming device which forms a first loop from the digital data services network side through the subscriber side and back to the digital data services network side, and a second loopback forming device which forms a second loop from the subscriber's side through the digital data services side and back to the subscriber side.  Further, the loopback testing starting system includes first and second loopback detection and resetting devices for resetting and stopping the detection operations of the first and second loopback controllers.          Based on this above configuration, the loopback test starting system is able to avoid a loopback closed circuit without prohibiting a loopback test from the subscriber's side, thus improving the quality of the maintenance control of the entire network.

Abstract: ABSTRACT       A mower having a belt tensioner that includes a belt engaging primary pulley swingably supported by a primary arm. A rod coupled to the arm carries a spring that acts to push the pulley into engagement with the belt.  The rod acts to pull the pulley away from the belt to release the tension in the belt for removal of the belt.  A handle attached to the rod is turned by the operator to positively swing the pulley away from the belt.  The handle may also be gripped by the operator's hand to lift that portion of the deck during operation to avoid gouging irregular ground conditions or striking obstructions.

Title: Three axis passive motion exerciser
Inventor: STEF FRANCINE
IPC: A61H1/02
Filed: 1992-01-21
Granted: 2002-12-10
Abstract: A three axis passive motion exerciser which moves the patient's foot in dorsal/plantar, valgus/varus and abduction/adduction movements. A microprocessor provides signals to control motors which drive cradles and a plate in the desired motions. Potentiometers provide positional feedback information about the actual location of the cradles and the plate, with series resistors providing feedback of the actual motor drive current values. The microprocessor monitors the positions of twa motions versus a master motion to keep the movements in synchronization. The movements are synchronized so that the end of the travel limit is reached for each axis simultaneously. The microprocessor further monitors the drive currents to prevent overcurrent conditions and the speeds to limit travel rates. A display and keyboard are-provided to allow the operator to monitor and change operating parameters, such as travel limits, force limits and session times.

Abstract: A co-controller provides communication between a standard voltage regulator controller and an LTC transformer, to enable the standard controller to be used in the operation of the LTC transformer. The co-controller generally consists of an interface circuit and a control circuit. The interface circuit receives status signals pertaining to the operation of an LTC transformer, as well as control signals from a voltage regulator controller, and buffers these signals for presentation to the control circuit. The control circuit is microprocessor based, and modifies the input signals from the interface circuit to provide the appropriate control signals required for the operation of the LTC transformer. The control circuit also implements a number of functions not available through a standard controller, such as current balance paralleling, overvoltage protection and correction for faults.
