Abstract: A multi-actuator capable vehicle headrest includes a headrest support and a multi-cam release mechanism mounted to the headrest support. The multi-cam release mechanism includes a first cam and a second cam. A headrest shell member is pivotally mounted to the headrest support through the multi-cam release mechanism. An actuator is mounted to the headrest shell member. The actuator includes a first actuator portion operable to disengage the multi-cam release mechanism based on a first input and a second actuator portion operable to disengage the multi-cam release mechanism based on a second input that is distinct from the first input allowing the multi-actuator capable vehicle headrest to transition between a deployed configuration and a folded configuration.

Abstract: Systems and methods for coordinating monitoring devices associated with a medium voltage distribution system. The systems include a data aggregation device, a first monitoring device associated with a first phase of the medium voltage distribution system, and a second monitoring device associated with a second phase of the medium voltage distribution system. The first monitoring device is configured to sense one or more parameters of the first phase, store the one or more stored parameters, and determine whether an event has occurred based on the sensed parameters. The first monitoring device is further configured to transmit a coordination signal to a second monitoring device in response to determining the event has occurred and a first event message to a data aggregator device in response to determining the event has occurred, wherein the event message includes one or more sensed parameters associated with the determined event.

Abstract: A terminal apparatus includes an ethernet channel that transfers ethernet traffic between an ethernet port and an external network port during a normal operation mode of the apparatus, and a Multimedia over Cable Alliance (MoCA) channel that transfers MoCA traffic between a MoCA port and the external network port during the normal operation mode. The terminal apparatus also includes a test system that bridges the ethernet channel and the MoCA channel during a test mode of the apparatus. Ethernet traffic received by the ethernet port is converted to MoCA traffic and transferred to the MoCA port, and MoCA traffic received by the MoCA port is converted to ethernet traffic and transferred to the ethernet port.

Abstract: A craft menu system, in a presently preferred embodiment, includes a network terminal like an ONT, having a processor and memory and multiple data ports, configurably coupled to a DTMF telephony (e.g., BUTT) test set for installation and testing. The installation, registration and testing information needed by a technician is provided by the ONT to the BUTT set display using convenient Caller ID signaling, and technician data entry is accomplished via the DTMF-enabled keys on the BUTT set. This system allows a single technician, equipped with current standard tools like a BUTT set and without the need for additional tools like a PC or PDA, to install and test a craft menu enabled ONT in a timely and efficient manner.

Abstract: An improved air brake hose coupling member for a rail car including a pivotally mounted pawl. The pawl has a ramp for engaging another coupling member. The engagement causes the pawl to be raised to an unlocking position automatically during coupling of the members. The axis of rotation of the pawl is in a plane substantially parallel to an inner coupling face of the member and substantially parallel to the longitudinal axis of a tubular body of the member. The coupling member also has a biasing element that causes the pawl to drop down into a locking position after coupling of the members is complete, thereby enabling the pawl to prevent undesired rotational decoupling of the members. A method for modifying existing non-locking coupling members with a pivotally mounted pawl.

Abstract: Method and apparatus for time lapse based measurement of impedance wherein a series of time measurements are made by voltage transitions with respect to a reference voltage across an unknown component and across a reference component with a known impedance. The time measurements are fed to a microprocessor or other computer means for calculating the impedance of the unknown component.

Abstract: Modulating system for electrically or pneumatically controlled chillers in which a sensor senses the space condition, in a controlled environment or space. Output signals from an enthalpy sensor or other sensor representing the space condition are fed to chiller modulator electronic controls and thence to the chiller modulator interface controls, be they electric or pneumatic. The sensor monitors the conditions in or returning from the controlled space or environment. By measuring both humidity and temperature, the enthalpy sensor generates an effective temperature or comfort level. The input signal from the sensor is compared to an operator adjustable set-point. If the measured condition is less than the set-point, an error signal is generated which is proportional to the difference multiplied by an operator-set sensitivity control.

Abstract: Circuit means for keying the transmitter of a flasher type depth sounder when the flasher arm motor is off. An alarm circuit is included in the depth sounder which sounds an alarm if the vessel moves away from a preset depth. When the flasher arm motor is on, a pulse is supplied by a magnet on the flasher arm passing over a pickup coil in the circuit. When the flasher arm motor is off, the pulse generating circuit is designed to provide a transmitter keying signal as well as to reset the alarm.

Abstract: Control system for limiting peak load demand and/or saving electrical energy by cycling the individual loads within an electrical distribution system. Electrical power usage in a distribution system is continuously monitored and compared to a pre-set limit. Loads can be added and cycled according to a limit set by the operator. Loads can also be dropped in response to a signal proportional to the electrical power usage in a distribution system within limits defined by the operator.
