    Abstract: Devices and methods for reading multiple types of RFID tags having different frequencies and/or encoding schemes are disclosed. One or more search signals covering a plurality of RFID bands are transmitted. A presence indication of an RFID tag in one of the plurality of RFID bands is detected. An interrogating signal having a carrier frequency tuned to a frequency at which the presence indication is detected is transmitted. A tag response signal comprising tag information associated with the RFID tag is received. A digital response signal based on the tag response signal is digital signal processed to obtain the tag information.

    Abstract: Systems and methods of extending battery life in inventory control devices are disclosed. A passive receiver configured to wirelessly receive an initiation signal having an associated energy field from a remote control system and to output a mode change signal is provided. The passive receiver is configured to be powered by an energy field associated with the initiation signal. A functional module coupled to the passive receiver and configured to be powered by a self-contained power source when the functional module is in an active mode is provided. The functional module is further configured to receive the mode change signal from the passive receiver and to change from an inactive mode to the active mode. The functional module draws more power from the power source in the active mode than in the inactive mode.

    Abstract: Systems and methods are described for simulating physical features of a projected keyboard in a sterile environment by incorporating a mechanical keyboard and a virtual keyboard. A keyboard projection apparatus projects light toward a mechanical keyboard. When a key is pressed, the keyboard projection apparatus tracks finger locations. User input is created by the keyboard projection apparatus and can be processed by a computer or other electrical equipment. By using an actual keyboard having simple mechanical components with the keyboard projection apparatus, the tactile feel can be realized and the keyboard can be easily cleaned or disposed of.

The power supply includes a power conditioner with an input configured to connect to an external source of electrical power, the power conditioner being configured to provide conditioned power on its output. The power supply also includes a transformer having a primary winding and a secondary winding, and a switching module coupled between the output of the power conditioner and to the primary winding of the transformer. The switching module has two modes of operation and a control signal input configured to accept a first control signal. The switching module includes a switching element configured to connect the power conditioner output to the primary winding of the transformer. The switching module operates in the first mode when the first control signal is in a first state, switching the first switching element at a first frequency and first duty cycle. The switching module operates in the second mode when the first control signal is in a second state, switching the first switching element at a frequency and duty cycle according to the first control signal.
