A method and system for calibrating a wireless sensor device are disclosed. In a first aspect, the method comprises determining a vertical calibration vector and determining a rotation matrix using the vertical calibration vector to line up native axes of the wireless sensor device with body axes. In a second aspect, a wireless sensor device comprises a processor and a memory device coupled to the processor, wherein the memory device includes an application that, when executed by the processor, causes the processor to determine a vertical calibration vector and to determine a rotation matrix using the vertical calibration vector to line up native axes of the wireless sensor device with body axes.

A sensor for inductively measuring the current in a conductor flowing through a recess in a printed circuit board. Wire loops on the printed circuit board function as the inductive current sensor. Combined with a voltage measurement, the energy being dissipated in the conductor's load circuit can be determined and transmitted wirelessly. Control circuits can be integrated with the metering hardware to enable the remote modulation of the load's power. The inductive sensor(s) can be used to track differences between the load's supply and return currents. If a fault is detected, the circuit can be broken for safety, serving a ground fault circuit interruption (GFCI) purpose. The claimed invention can report measurements in real time, providing time series data for analyses sufficient to detect or identify an anomaly in the function and operation within a system's load or electrical power distribution network.

Systems and methods for verifying and monitoring employees are provided. Employees call-in to the system at scheduled times. If an employee misses a scheduled call-in, an alert can be generated. An employer notification process can generate the alert, notifying a supervisor of the employee's missed call. The alert can include the employee's name, the location of the employee, and the time he/she was supposed to call. Such systems and methods can be used to verify that a worker is at the proper location at the proper time and awake and alert during the entire time period that he/she is supposed to be working.

Described are techniques for monitoring use of a shared resource, such as physical resource, for example, a motor vehicle. The techniques include receiving an electronic representation of a user's identity, by a vehicle access application executable in a computing system in the vehicle, sending by the computing system to an identity and access management system the received electronic representation of the user's identity, receiving by the computing system from the identity and access management system credentials that validate the electronic representation of the user's identity, and enabling by the computing system starting of the vehicle when the computing system receives the credentials that validated the user's identity.

A system and method for providing awareness in a hospitality environment are presented. In one embodiment, a vertical and horizontal array of set-top boxes is provided and each set-top box includes an identification corresponding to the room in which the set-top box is placed. Each set-top box includes a wireless transceiver that periodically transmits an identification beacon that is received by a proximate wireless-enabled interactive device. The proximate wireless-enabled interactive device, in turn, broadcasts data packets including an indication of the strength of set-top box identification signals received. The broadcasts are received by a server via an array of wireless routers. The location of the proximate wireless-enabled interactive device is determined based on the signal strength information in the data packets.

A lottery ticket dispenser array includes ticket bins, with each bin defined by a housing for receipt of a supply of interconnected lottery tickets. Each bin has an electronic drive mechanism that dispenses the lottery tickets therefrom. A slot is defined in the back side of each bin housing through which the lottery tickets are dispensed from the internal space, and a separation device is adjacent the slot. A calibration field is located relative to the slot such that the lottery tickets pass alongside the calibration filed in a travel path of the lottery tickets through the slot. An optical scanner is disposed internal to the housing at a location to read the marks in calibration field. Based on a position of a forward edge of a ticket in the calibration field, a control system determines an adjustment to a predefined length of the leading ticket to advance in a subsequent dispense cycle.
