Abstract: A portable system for reminding a patient and keeping track of the prescription and use of medications. The system comprises a portable unit and a software application program loaded in a PC-type computer. The portable unit consists mainly of a compact portable housing which contains an LCD display; audible alerts; pushbutton controls; battery power; and electronic circuitry to receive, store and display data. The portable unit can be programmed with dosage information regarding the particular medication, track when a particular medication has been taken, and sound an alarm when time to take another dose. The portable unit also checks for contraindications and warns of adverse reactions the patient would have with a particular drug or if a particular drug cannot be mixed with another drug presently being taken by the patient.

Abstract: An apparatus and method of reducing the size of a servo burst and thus increasing the disc surface available for data storage is accomplished by uniquely encoding track information in the gray code of a servo burst on a disc. Each track has a unique sequential track identification number assigned to it. A plurality of sets of servo sectors on each track are encoded with a modulo operation of the track identification number for the track each using a unique modulus. Preferably the sectors are grouped into two sets, i.e., even numbered sectors on each track are modulo encoded with a first modulo operation of the track identification number for the track using a first modulus and odd numbered servo sectors on each track are modulo encoded with a second modulo operation of the track identification number for the track using a second modulus. Decoding the absolute track address is accomplished by decoding the modulo numbers and comparing the even sector modulo numbers to the odd numbered sector modulo numbers.

Abstract: A tilt compensation method, circuit and apparatus utilizes a two axis tilt sensor or two single axis tilt sensors for alerting, a user and/or compensating a surveying instrument for off vertical alignment above a reference point when the instrument support is free to move about the reference point, e.g., when mounted on a monopod support.

Abstract: A closed loop wire saw loop, a method for making the closed wire saw loop, and an apparatus and method for slicing a work piece, in particular, a polysilicon or single crystal silicon ingot, utilizing a closed loop of diamond impregnated wire in which the work piece (or ingot) is rotated about its longitudinal axis as the diamond wire is driven orthogonally to it and advanced from a position adjoining the outer diameter ("OD") of the ingot towards its inner diameter ("ID"). In this manner, the diamond wire cuts through the work piece at a substantially tangential point to the circumference of the cut instead of through up to the entire diameter of the piece and single crystal silicon ingots of 300 mm to 400 mm or more may be sliced into wafers relatively quickly, with minimal `kerf` loss and less extensive follow-on lapping operations. The closed wire saw loop is made by squaring and welding the wire ends together and then twice heat treating the weld at about 1500 F.

Abstract: An apparatus and method for accurately determining a target distance in adverse weather conditions utilizing both LASER and RADAR is disclosed. The radar signals are used to determine an approximate range which is then used as a gating window for the determination of which laser reflection is from the actual target as opposed to a reflection from the atmospheric interference. The method basically comprises the steps of initiating a radar pulse in the direction of a target and receiving a reflection, transmitting a laser signal and receiving a plurality of reflections, determining an approximate range based on the radar signals, and using this approximate range to ascertain which of the laser reflections is from the target. This determination is preferably made by generating a gating signal and gate width from the radar signals and passing the set of laser range signals through the gate to eliminate the false signals and select the signal that survives the gate as the accurate target range.

A preferred embodiment of the apparatus is an interactive exercise video system which utilizes a bicycle, a bicycle wheel speed detector, an interface unit connected to the wheel speed detector and to a conventional game controller connected to a conventional video game CD player, which is in turn connected to a TV.

The variation of the video frame rate is accomplished by modifying the duration time stamp on each video frame which is used by the player control program so as to change the sequential time at which each frame is called for display by the conventional video player.

Abstract: An adaptive multidimensional media asset rating system and method for selective play of a media asset includes an N-dimensional rating vector encoded into the leader portion or meta-data portion of a media asset. This N dimensional rating vector has a magnitude value for each of the N dimensions and is assigned to each asset by the asset producer.

The rating vector is then read from the asset by the filter system in or connected to the media asset playing device such as a TV, videotape recorder/player, radio receiver CD player, or other reception device prior to processing the asset for viewing. The user programs into the filter system coupled to the asset player or reception device a threshold N dimensional preference vector which has a magnitude value for each of the N dimensions.
