Abstract: A system and method for managing distribution of wideband radio frequency signals includes detecting an impedance signature of a device connected at the end of transmission medium. A switch is opened to apply a wideband radio frequency signal to a transmission medium for distribution. A biasing voltage can be applied to the transmission medium based on the detected impedance signature. A signal conditioning circuit is selected based on the amplitude of the biasing voltage, and the wideband radio frequency signal is distributed to an output device.

Abstract: A low power rf control system includes a controller that operates at a low clock speed when an associated rf receiver is deenergized and a high clock speed when the controller energizes the receiver. The receiver can be on for a short period, off for a short period when no preamble pulses from a remote control device are received, on for a short period, and then off for a longer period until the next cycle. The receiver remains on to process a command signal when a preamble signal is detected. A DC-DC down converter can be used as a power supply for the receiver, and a SAW resonant circuit can be used as an IF oscillator for the receiver. An LC filter can be associated with the receiver for filtering the IF signal.

Abstract: In an exemplary embodiment, a drug delivery device for driving an electrotransport current through a body surface of a user is provided. The device includes a patch with two electrodes and one or more reservoirs storing a therapeutic agent. The one or more reservoirs release the therapeutic agent into the body surface of the user when the reservoirs are positioned over the electrodes to form an electrical path for the electrotransport current. The device includes a controller which controls a controllable power supply to drive the electrotransport current through the body surface of the user in a predetermined profile.

Abstract: A device for the detection of tailgating between vehicles on a roadway. The device may emit ultrasonic signals on to a roadway and receive said reflected signals. The device has a processor adapted to use the received signals to determine the presence or absence of a vehicle. The processor also determines whether a vehicle is tailgating another vehicle by detecting if the time spacing between two sequential vehicles traveling in the same direction in the same lane is two second or less. The processor alerts a remote receiver when tailgating is detected. The device may also include a camera to take pictures of any vehicle determined to be tailgating. The device is preferably compact and easily portable.

Abstract: An implantable infusion pump system is disclosed. The pump system preferably includes an implantable pump and a removable module. The module may provide for varying flow rates of fluid being dispensed from the pump or may provide for a constant flow rate of such fluid. In the case of varying flow rate capabilities, the module preferably includes one or more sensors to determine information relating to the flow rate, electronics for analyzing the flow rate information, and a mechanism for physically altering the flow rate. Methods of dispensing a medicament to a patient are also disclosed, as are variations of the pump system.

Abstract: A method for encrypting and/or hiding data to a storage device is given. The method is based on any of the following algorithms: 1. Formatting any storage uniquely while storing the information about the unique format to a Geometrical Cell Location Table (GCLT); 2. Storage-sectors, based on standard formatting are uniquely shuffled whiled creating Shuffled LBA (SLBA); 3. A method of encrypting (82) a sector-content by using more than one key (81); 4. “Dating” prevention of the sectors content in a hard disk drive by electro-magnetic instruments, this is achieved by renewing data of randomly selected sectors (83); 5. A method for keeping the encrypted content of the hard disk drive in its maximal encryption power complexity by preserving hard disk drive fully filled with encrypted data (even empty sectors are filled with encrypted data). By implementing the above algorithms to a hard disk drive, the encryption complexity power stays constant in time.

Abstract: An air conditioning system cools air within an area. An air conditioner controller defines information based on input data from door and window open status sensors and a return air monitor sensing the dry bulb temperature and the wet bulb temperature or relative humidity of the air within the area being cooled by the air conditioning system and shuts down the system when specific conditions exist. The defined information is transmitted to a remote host device which retains and presents the transmitted information or information derived therefrom.
