The invention provides a system and method for easy and reliable connection of patient-originated medical data through a simple port of a computer to a dedicated web site. A device originating medical data, such as an implanted pacemaker, downloads data into a transmit / receive device, and the data is then transformed in an interface unit to be accepted by a simple port of a computer, e.g. a keyboard port or a mouse port. The patient logs on to a dedicated web site, and transfers the data along with typed input to the web site for analysis. Following analysis, a reply message is sent back to the patient, which may include a control instruction for modifying or reprogramming the operation of the device that is used to originate the medical data. For a pacemaker application, the data transformation is done at a simple interface unit that is portable and easily manipulated by the patient. For other applications such as monitoring data from a diabetic, the data is transformed by the interface unit, and may be stored daily in the PC and transmitted to the web site after collection of a predetermined number of days of data.

The present invention provides an improved antenna system that, in one embodiment, includes an antenna array comprised of a plurality of elements, each of which is capable of providing a signal. Also included in the improved antenna system is a multi-beam beamformer for producing two spatially independent overlapping beams from the signals provided by two different subsets of the antenna array. The phase of the two beams is compared to realize an interferometer that can provide high or fine resolution data on the position of an object relative to the antenna system. The amplitude of the two beams can also be compared to obtain coarse data on the position of the object. The beamformer includes a switching network for selecting which elements of the antenna array form the two subsets. This permits, for example, the position of the beams to moved, the baseline of the two beams to be varied, and / or the beam width of the beams to be altered. To reduce adverse aerodynamic effects in certain applications, the antenna array is located conformal to the exterior surface of the body on which the array is mounted. Further, to reduce temperature related problems associated with high speed movement of the body on which the array is located, the array is located on the side of the body, as opposed to the front of the body. The side location also provides space for other types of sensors that are preferably located adjacent to the front surface of the body.

Wireless communications between a digital camera and a printer dock are established in a simple manner. A processor (10f) of a digital camera (10) detects a printer dock (12) within communication range via a communications circuit (10e) and its ID is acquired. The processor (10f) uses the acquired ID to transmit a sequential power transmit request to the printer dock (12). In response to this request, the printer dock (12) wirelessly transmits power from a communications circuit (12b) and a transmitting coil (12c). When power is received by a receiving coil (10a), it specifies that printer dock (12) is the communication party, and photographed data is wirelessly transmitted using an ID of the specified printer dock (12).

The present invention dispenses hot coffee or other beverage by the cup at a selected temperature, which can be varied from cup-to-cup. The beverage is brewed in a conventional way, and in one embodiment is stored in a conventional holding tank at elevated temperature. The holding tank communicates with two smaller reservoirs. A quantity of beverage is stored in a first reservoir at an elevated temperature, at or above the maximum desired dispensing temperature. A second quantity of beverage is cooled and stored in a second reservoir at a lower temperature, at or below the minimum desired dispensing temperature. When a cup of beverage is to be dispensed, the temperature is selected, and a quantity of beverage is dispensed from each of the reservoirs, proportioned so that the resulting dispensed beverage is at the selected temperature. In another embodiment, the first reservoir is omitted, and beverage from the holding tank provides the elevated temperature beverage for mixing. In several other embodiments, no cooling mechanism is needed. Instead, the holding tank is at a cooler temperature than the lowest vend temperature, and the beverage must be heated to the hot reservoir temperature and, in one embodiment, the cold reservoir temperature. In another embodiment, the holding tank functions as a cold reservoir. In still another embodiment requiring no heaters, the holding tank is eliminated, and the beverage is held in insulated chambers at the higher and lower temperatures.

A capacitive touch panel is provided capable of detecting multiple simultaneous touches. The touch panel delivers sets of capacitance signal values to a processor which computes the coordinates of single or multiple touch locations on the touch panel. The processing of each set is performed by (i) identifying the sensing element having the largest capacitance signal value; (ii) defining a region around that sensing element; and (iii) repeating the process iteratively, wherein each subsequent identifying step excludes signals that lie in previously defined regions. A multi-touch sensor is thus provided in which the signal processing is based on successive definition of regions or sub-blocks in the touch: panel. The touch location in each region can be determined more accurately by then applying interpolation between the adjacent signal values. This allows for position resolution at a finer scale than that defined by the touch panel's electrode patterning.

A heart stimulator has an atrial and ventricular pulse generator for producing atrial and ventricular stimulation pulses, an atrial sensor for sensing atrial signals and an evoked response detector for detecting the occurrence of incipient fusion beats from measured ventricular signals. A determination unit determines an incipient fusion AV-interval from the sensed atrial signals and the detected fusion beats, and a controller controls the pulse generator to deliver stimulation pulses at a controlled AV-interval which is shorter than the incipient fusion AV-interval. The evoked response detector includes an averaging unit which forms an average amplitude value of the measured ventricular signals during a predetermined time window of each cardiac cycle, and a comparator which compares the average value for each cardiac cycle with a predetermined limit criterion, and supplies the result of the comparison to the determination unit for determining a measured ventricular signal resulted from an incipient fusion beat or a completely stimulated capture.

A medical system is provided comprising a sensor unit and a receiving unit is provided, the sensor unit being adapted to generate sensor data indicative of a time-dependent characteristic of a subject, and transmit data to a receiver at intervals determined by an analysis of time-dependent changes in the generated sensor data, the receiving unit being adapted to receive sensor data at a non-predetermined rate. By this arrangement sensor data can be transmitted only when considered necessary in accordance with a predetermined strategy, this reducing the energy consumption associated with the transmission of data. The strategy may set out that the transmission of sensor data is skipped in case there is no or only a small change in an actual sensor data value. On the other hand, in case of rapid changes in sensor data values, sensor data may be transmitted at higher rate.
