Filed: 1994-01-21
Abstract: A subcutaneous radiation reflection probe for measur-ing oxygen saturation in living tissue includes an elongate drive shaft (4) on one end of which is detachably coupled to a mounting cup (20). The mounting cup (20) includes a hol-low (48) for receiving and holding a base element (40) on which is mounted a spiral needle (24) which coils outwardly from the mounting cup (20) to terminate in a pointed end (24a). A window (60) is formed in the spiral needle (24) near the pointed end (24a) thereof for receiving and holding a radiation emitter, such as a light emitting diode (64). A radiation detector (44) is disposed on the base element (40) within the coil of the spiral needle (24). The probe may be used to measure oxygen saturation in living tissue, such as a fetal scalp, by inserting the mounting cup (20) and drive shaft (4) through an introducer (36) into a woman's vagina until the spiral needle (24) contacts the fetal scalp.

Title: Radio communication apparatus
Inventor: USHIDA BUNJI
IPC: H04W52/02
Filed: 1995-08-21
Abstract: The present invention aims at reducing power consumption in a radio  communication  apparatus  having  a  plurality  of  radio sections capable of selective switching by controlling power to be supplied to each of the radio sections.   To this end, the apparatus includes: a power-supply condition memory section in which conditions for controlling power supply are previously set and stored; and a control section for controlling power supply to the other radio sections based on the value of a reception-signal quality signal from a currently selected radio section and the conditions  previously set and stored to said power-supply  condition  memory  section.    A  reference  value  for controlling power supply is previously set and stored to the power-supply  condition  memory  section  as  a  power-supply condition.   At the control section, the value of a reception-signal quality signal from the currently selected radio section is compared with the reference value previously set and stored to said power-supply condition memory section.  Power supply to the other radio sections is stopped when the receiving status of the  currently  selected  radio  section  is excellent and power supply to the other radio sections is resumed when the receiving status is poor.

Patent CA-2161753-A1 (CA)
Inventor: OTEMA MARTIN
IPC: A47B57/42
Filed: 1995-10-30
Abstract: The invention provides an adjustable supporting means such as a shelf bracket having means for making fine adjustments in the attitude of the bracket relative to the supporting surface, which allows the shelf to be levelled both longitudinally and transversely, and substantially facilitates alignment with adjacent shelves. In one embodiment this is accomplished by pivotally suspendinga shelf clip from a vertical mounting gusset designed to be hung on the supporting surface, such that the attitude of the clip relative to the supporting surface can be adjusted. Adjusting means such as an adjusting screw engaged in a hole tapped through the clip bears against the mounting gusset to limit the travel of the clip under the weight of the shelf. The position of the adjusting screw thus determines the attitude of the portion of the shelf being supported by the clip. The invention further provides a standard system including a mounting bar having a series of openings for mounting the supporting means such as a shelf bracket, hook, hangaror the like at a desired position along the mounting bar. The mounting openings may be spaced more closely than in a conventional slotted standard and are much less conspicuous and thus more visually appealing. The mounting bar bay be provided with hooks for engaging a slotted standard or tabs for securing the mounting bar directly to the structure of a display unit or the like.

Title: Method and apparatus for indexing searching and displaying data
Inventor: EGGER DANIEL
IPC: G06F16/31
Filed: 1994-06-13
Abstract: A computer research tool (26) for indexing, searching and displaying data is disclosed. Textual objects and other data in a database (54) are indexed by creating a numerical representation of the data. An indexing technique called proximity indexing indexes the data by using statistical techniques and empirically developed algorithms. Using proximity indexing, an efficient search for pools of data can be effectuated. The Computer Search progam, called the Computer Search Program for Data represented in Matrices (CSPDM), provides efficient computer search methods. The CSPDM rank orders data in accordance with the data's relationship to time, a paradigm datum, or any similar reference. The user interface program, called the Graphical User Interface (GUI), provides a user friendly method of interacting with the CSPDM program and prepares and presents a visual graphical display. The graphical display provides the user with a two dimensional spatial orientation of the data.

Title: Method and apparatus for controlling bias levels
Inventor: LEWIS DAVID EARL
IPC: G11B11/10
Filed: 1996-02-15
Abstract: An apparatus for controlling the strength of a magnetic field, comprises a first controller (14), a second controller (15), a digital-to-analog converter (16), a current driver (17), and a bias coil (18). The first controller (14) determines the position of the focal point of a lens (29) and passes it to the second controller (15), which provides a digital signal related to the position. The digital-to-analog converter (16) converts the digital signal to a driver voltage and passes the driver voltage to a current driver (17), which provides to the bias coil (18) a bias current related to the driver voltage. The bias coil (18) produces a magnetic field having a strength related to the bias current. The second controller (15) accounts for stray magnetic fields in creating the digital signal. The stray magnetic fields may be constant or may vary in strength based on position of the objective lens (29), circumferential velocity of the storage medium (2, 4), or longitudinal velocity of the storage medium (2, 4). Furthermore, the apparatus may comprise a current sensor (26) for measuring the bias current, and a feedback device for providing to the current driver (17) a feedback voltage related to the bias current.

Filed: 1995-12-18
Abstract: A sugarless non-tack chewing gum having excellent cohesive properties and flavor is prepared using a non-tack gum base which is typically less cohesive or even crumbly.  The lack of cohesiveness in the gum base is overcome by adding, to the chewing gum, a syrup blend including glycerin with evaporated hydrogenated starch hydrolysates and water.  The syrup blend is preferably prepared by coevaporating a mixture of glycerin with a conventional aqueous hydrogenated starch hydrolysate solution, ln order to remove much of the water.  The syrup blend acts as a binder for the gum base and chewing gum ingredients without causing the gum to adhere to teeth and dentures.
