摘要:
Described is a system and method for detection using an ultrasonic wave. The system may include a first arrangement and a second arrangement. The first arrangement may include a transmitter and a receiver. The transmitter transmits an ultrasonic wave along a surface on which items are to be stored and the receiver receives the wave after it has passed over the surface. The second arrangement receives from the first arrangement data corresponding to properties of the received wave. The second arrangement compares the properties of the received wave to properties of the transmitted wave to generate current condition value. The second arrangement determines based on the current condition value and calibration data a current condition state corresponding to a degree of the surface currently occupied by the items. The calibration data includes at least one calibration value and a corresponding calibration condition state.

Energy efficient roaming of a mobile device is described. The mobile device can include a sensor for sensing a motion of the mobile device to generate a sensor signal. A radio is capable of communicating with a wireless network. A processor activates the radio in the mobile device. The processor generates an environmental profile of the mobile device based at least on the sensor signal. A memory is coupled to the processor for storing the environmental profile. The processor deactivates the radio when the environmental profile indicates that the rate of motion of the mobile device is above a predetermined threshold for a first period of time. The processor reactivates the deactivated radio when the environmental profile indicates that the rate of motion of the mobile device is below the predetermined threshold for a second period of time.

An arrangement for and a method of collecting and displaying information in real time along a line of sight from a human operator to remote targets located at variable distances therefrom and identifiable by machine-readable indicia. A two-dimensional image is automatically projected along the line of sight on the target alongside the indicia while maintaining the image size relatively constant over an extended range of working distances.

A system for staging a mobile device is described. The mobile device includes a processor that executes a software application. A memory stores a unique identifier for the mobile device. The unique hardware identifier is readable by the software application and unreadable by any system that is external to the mobile device. The mobile device also includes a radio frequency identification (RFID) tag associated with the mobile device. The RFID tag stores a unique serial number that is readable by a staging system external to the mobile device and by the software application. The staging system encrypts a staging profile using both the unique serial number and the unique hardware identifier to create a device-specific key. The staging system writes the encrypted staging profile to the RFID tag.

Described is a method and system for detecting a first trigger event using a trigger device (10) , the trigger device including trigger sensor (2) and a trigger tag (4). Listening on a predetermined radio frequency band by an interrogator for an activation signal, wherein the activation signal is generated by the trigger tag, the activation signal including a unique identifier of the trigger tag and receiving the activation signal. The activation signal is then validated as being received from an associated trigger tag and the interrogator is activated into an interrogation mode upon validation of the activation signal.
