摘要： A control system for a bathing installation which has one or more electrically powered devices. A line voltage service is connected through a GFCI to power the electrically powered devices, the GFCI adapted to interrupt the service upon detection of a ground fault. A trip circuit may induce a ground fault and trip the GFCI in response to a trip signal, thereby disabling application of electrical power to the electrically powered devices. An electronic circuit is responsive to a fault condition for generating the trip signal.

摘要： A bath tub cushion for lining one end surface and a portion of a bottom surface of a bath tub includes a back portion having a number of fluid impermeable chambers formed therein. A fluid communication device is disposed in fluid communication with an interior portion of the chambers for inflating and deflating them as necessary. An anti-slip mechanism is disposed on a back surface of the back portion which engages an end of such bath tub to prevent movement during use. A bottom portion extends toward an opposed end of such tub and is connected to a bottom edge of a front portion of such back portion for supporting a person's hips during bathing. There is an additional anti-slip mechanism disposed on a bottom surface of the bottom portion which engages bottom surface of such bath tub for preventing movement of the bottom portion during use.

摘要： A motion control system and method that includes a central controller configured to generate first and second demand control signals to be used to define actuation motion of respective first and second actuators. The central controller is in communication with first and second nodes by way of a data network, each node including at least a respective actuator configured to implement at an actuator time a motion or force-related effort based upon the respective demand control signal. Each node also includes a memory configured to store at least one respective propagation delay parameter related to a signal propagation delay between the central controller and the node. A timing mechanism establishes timing at each node based on the respective propagation delay parameter so that the actuator time at the nodes occurs simultaneously. Strictly cyclic and/or full-duplex high-speed communication can be supported. The network can be wired in a ring or as a tree and with twisted pair cabling or fiber. The central controller issues demand signals to the nodes that are actuator, servo motor drive, and/or I/O devices. The central controller can also provide a timing message that is used by the nodes, in conjunction with local delay correction circuitry, so that the simultaneous acquisition of data and the simultaneous implementation of controlled action occur.

摘要： Systems and methods of supporting communications over a common network connection in a master-slave field bus network with a first type of packet formatted with a time-sensitive protocol and a second type of packet formatted with a non-time-sensitive protocol are provided. The slave devices are configured with filters to prevent the first type of packet from reaching a configurator and the second type from reaching a master device. The slave devices are also configured with arbitration logic so that the packets formatted with the time-sensitive protocol are provided with a priority over the packets formatted with the non-time-sensitive protocol.

摘要： A headboard support bracket is disclosed that, when used with independent legs on a box springs, can eliminate the need for a metal frame for support of the headboard associated with the box springs. Further, the use of the bracket eliminates the need for affixing the headboard to the wall of the room, thereby precluding relocation of the bed without removal of the headboard from the wall. The headboard support bracket is symmetrical so that it can be used on either corner of the box springs without the need to resort to "right" and "left" were the bracket asymmetrical. The bracket includes indicia means for positioning the headboard support bracket properly on the box springs.

摘要： A control system for a pool and spa. Main line voltage is provided through a single line voltage service and a single ground fault circuit interrupter circuit, facilitating a ground fault test and simplifying installation. The control system acts as a power distribution system for controlling the pool and spa equipment, with a circuit board assembly including individual fuse protection devices and switching circuits. A test algorithm is included, wherein the control system is disabled from normal operation if the GFCI test fails. The pool operator manually enters a water fill command, and the controller system automatically opens the fill valve for a predetermined time interval, and then automatically closes the valve. An emergency disconnect switch is mounted near the bathing area, connected by low voltage wiring to the controller system cabinet. The controller system senses the emergency switch closure and disconnects line voltage to the line voltage loads. The emergency switch closure also remotely induces a ground fault, tripping the GFCI. A sensing circuit allows the controller system to sense the presence of the emergency switch system, and issues a warning and prevents normal operation of the pool and spa system if not connected. A gas pressure sensor monitors the natural gas line, and the heater is disabled and a warning given under low pressure conditions. Abnormal filter backpressure triggers a warning when the filter needs service. A temperature sensor has parallel sensing elements in a common housing to provide separate sensing circuits.
