Abstract: A motion sensing necklace comprising includes a pendant attached to lower ends of two lanyards. The pendant includes a help button for a user to generate a signal for help, and a battery to power the motion sensing necklace. A neck strap is attached to upper ends of the first and second lanyards. Two motion sensors are located within opposing ends of the neck strap. A microprocessor located within the neck strap processes signals from the motion sensors to determine whether motion has occurred. A transmitter or transceiver located within the neck strap transmits motion detection signals and alerts generated by the microprocessor.

Abstract: Devices and methods of using a personal emergency reporting system device is described. The personal emergency reporting system (PERS) device wakes up based on timing, manual activation or an accelerometer in the PERS device detecting an abnormal condition. The PERS device measures the orientation and correlate and sends statistics to a console. The PERS device determines whether a predetermined threshold has been met to determine whether a fall event has occurred or whether to enter a more active monitoring state. The PERS device also determines whether it is appropriate to transmit an alarm to a central monitoring station via the console and transmits the alarm if desired.

Abstract: A system and method of using a combination of portable devices including wearable devices and tags and fixed devices including plug-in readers that are able to communicate using a short range wireless technology is described. The environment in which the fixed devices are disposed include residential, vehicle and commercial/work areas. The environment is able to detect the presence and absence of particular portable devices, determine whether personalized triggers exist and act accordingly based on information stored in a server or cloud-based storage. The actions in the environment include security, environmental controls, and alert transmission.

Abstract: A fall detection method determines a fall detection algorithm based on sensor data aggregated from a plurality of fall detection devices. Sensor data is obtained from one of the plurality of fall detection devices not included in the aggregated sensor data. A probable fall event of the obtained sensor data is determined based on the fall detection algorithm. An alarm signal is generated based upon the determination of the probable fall event. A validity of the probable fall event is determined, and the fall detection algorithm is refined using the obtained sensor data and the validity of the probable fall event each time sensor data is obtained from any of the plurality of fall detection devices.

Abstract: A method for monitoring relative position of a carriage and a recording medium in an inkjet printing system having a roller for advancing the recording medium along a recording medium advance direction, the method includes sending light from a light source toward at least a portion of the roller; receiving reflected light in a two-dimensional sensor mounted on the carriage; sending a signal from the two-dimensional sensor to a controller, wherein the signal indicates the pattern of reflected light received by the two-dimensional sensor; comparing the received signal by the controller to a signal stored in memory; and calculating a shift between the received signal and the signal stored in memory.

Abstract: An inkjet printing system includes a roller for advancing a recording medium along a recording medium advance direction; an inkjet printhead that ejects drops of ink; a carriage for moving the printhead along a carriage scan direction that is substantially perpendicular or perpendicular to the recording medium advance direction; one or more motors for driving the roller and moving the carriage; a two-dimensional sensor mounted on the carriage which two-dimensional sensor is configured to sense either: a) the recording medium; b) the roller and the recording medium; or c) the roller; and a controller for receiving electrical signals from the two-dimensional sensor and for controlling the one or more motors.

Abstract: An inkjet printhead that receives one or more detachably mountable ink tanks, the inkjet printhead includes an ink tank holding receptacle that receives the one or more detachably mountable ink tanks between a first and second wall; a spring disposed on the first wall of the printhead to provide a biasing force in a direction that pushes the detachably mountable ink tank away from the first wall of the printhead and which biasing force must be manually overcome in order to properly install the one or more detachably mountable ink tanks in the ink tank holding receptacle of the printhead.

Abstract: An ink tank having a tank housing; an electrical contact on the housing; an ink outlet port disposed on the housing; and at least one projection disposed adjacent the electrical contact on the housing, wherein the projection is configured for engaging a leaf spring of an inkjet printer. The leaf spring exerts an out and away pivoting force on the projection so that an electrical connection destination for the electrical contact is prevented until the ink tank is completely installed.

Abstract: An inkjet carriage that receives a print cartridge, the inkjet carriage includes a holding receptacle having a wall, wherein the holding receptacle is configured to receive the print cartridge; and a spring disposed on the wall of the holding receptacle to provide a biasing force in a direction that pushes the print cartridge away from the wall of the inkjet carriage and which biasing force must be manually overcome in order to properly install the print cartridge in the holding receptacle of the inkjet carriage.

Abstract: A method for measuring dimensions of a stack of medium in a media input location of an imaging system, includes emitting light along a direction that is at a predetermined angle with respect to the normal of the planar surface of the media input location. An array of photosensors are disposed along an array direction that lies in a plane defined by the direction of the light and the normal of the planar surface. The photosensors receive a spatially-varying pattern of light reflected from a surface that is substantially parallel to the planar surface of the media input location to provide corresponding electronic signal data from the photosensor array for subsequent transmission to a printing system controller. The varying electronic signal data is used to provide a measurement of the one or more dimensions corresponding to the stack of medium.
