Title: Low power current-to-frequency converter circuit for use in implantable sensors
Inventor: GORD JOHN C
IPC: A61B5/00
Filed: 1998-09-11
Granted: 2006-01-24
Abstract: A low power current-to-frequency converter circuit provides an output frequency signal F OUT having a frequency that varies as a function of a low level analog input current signal. The analog input curren t signal is typically generated by an implantable sensor element, designed to sense a particular substance or parameter within body tissue or fluids to which the sensor is exposed, with the magnitude of the analog signal providing a measure of the sensed substance or parameter. Conversion of the low level analog current to the output frequency signal facilitates transmission of the data signal over a shared data bus and other digital processing of the data signal. The current-to-frequency converter circuit is fabricated from low power FET-base d integrated circuits, and includes an operational amplifier having its positive input terminal connected to a storage capacitor that is charged by the analog input current signal, a voltage-controlled oscillator driven by the charge (voltage) on the storage capacitor that produces the output frequency signal, and a charge pump circuit that pumps a discrete amount of charge off of the storage capacitor during each cycle of the output frequency signal.

Abstract: An optical diagnostic tool for allowing an observer to obtain optical information regarding various characteristics of the eyes of an intended patient. The tool includes an enclosure defining a peripheral wall, a patient end wall and an observer end wall. An optical dividing wall is positioned within the enclosure. The optical dividing wall divides the enclosure into a first and a second optical chamber, allowing for the creation of distinct lighting pattern in the first and second optical chambers. A first and a second patient eye aperture both extend through the patient end wall. The first and second patient eye apertures individually establish visual communication respectively with the first and second optical chambers. An observer visual access structure allows the observer to obtain selective optical access to either one or both of the first and second optical chambers and to either one or both of the corresponding first and second patient eye apertures. A selective light emitting structure mounted within the enclosure allows for the creation of the predetermined distinct lighting patterns in the first and second optical chambers.

Granted: 2008-06-03
Abstract: A system notifies a first user of a mobile communication device about status of other users in a mobile communications system. The system sends a signal from the mobile communication device to a service node in the mobile communications system. At the service node, a list is determined indicating to other users that the first user wants to know the status of. The status of each of the other users on the list is then determined, and transmitted from the service node to the mobile communication device. The signal from the mobile communication device to the service node may be generated in response to the mobile communication device being powered on, and may itself include an indication that the mobile communication device has been powered on. Upon receipt of this indication, the service node may determine other lists in which the first user is listed, determine a corresponding other user for each of the other lists, and send a notification to each of the corresponding other users indicating that the first user has gone on-line.  Users of communication devices may thereby be informed of updated status of other users they are interested in. Other types of status include indications of going off-line, present location, and whether a given user is associated with voicemail and/or e-mail services. The service node maybe home location register.

Granted: 2005-07-26
Abstract: A large round baler is equipped with a net wrapping mechanism for wrapping a bale with net material that is wider that the width of the baling chamber so that the net material extends over the opposite ends of the bale. The baler has a baling chamber defined in part by a plurality of bale-forming belts mounted in side-by-side relationship on a plurality of belt support rolls extending between opposite sidewalls of the baling chamber. The net material is fed beneath the discharge gate of the baler to a crop inlet located between a lower front belt support roll carried by the discharge gate, the net being carried into the baling chamber by a fore-and-aft runs of the belts that extend between a lower rear and the lower front belt support roll, and carry the net along a guide surface defined by a plurality of channel members respectively located beneath the fore-and-aft runs of the belts. In order to ensure that the net material arrives at the baling chamber at width greater than that of the baling chamber, spiral rings are mounted at opposite ends of the lower rear belt support roll and spreader rings are mounted at the opposite ends of the lower front belt support rolls, the spiral rings being located outboard relative to the spreader rings, with a major portion of the spreader rings being located outboard of the opposite sidewalls of the baling chamber. In order to keep rogue or stray crop stems from interfering with the net material so as to prevent it from being spread to its full length and fed, shielding is provided inside the baling chamber at a location above the lower rear roll. Wrap around shields are provided to shield the spreader rings from crop that is delivered into the baling chamber and various other structures are provided for preventing the accumulation of rogue or stray crop in the vicinity of the spreader rings and other areas in the path of net travel.
