Title: Combination Nursing Blanket and Cradling Aid
Inventor: LARSON KAREN MARIE
IPC: A41D1/215
Filed: 1996-06-10
Abstract: A combination nursing blanket and cradling aid for use by a care giver when breast-feeding or cradling an infant has a nursing blanket and a tubular pad. The nursing blanket is attached to the tubular pad which is worn on the care giver's arm. The nursing blanket is of a size and shape adapted for sheltering the infant and providing privacy to the care giver when the baby is being breast fed. The nursing blanket can be made with a length suitable for being loosely draped from where it is attached to the pad, across the care giver's body and over the care giver's opposing shoulder. The pad encircles the care giver's arm providing a cushion for the infant's head and for the care giver's arm which may be supported on a hard surface, such as a chair's arm rest.

Title: Dataform readers and methods
Inventor: WANG YNJIUN P
IPC: G06K7/10
Filed: 1995-10-31
Abstract: Dataform readers and methods provide operation with a se-quence of overlapping exposure periods for successive lines of sensor elements of an array. Also, the exposure periods for successive lines of sensor elements, or successive subsets of lines, can be indepen-dently determined. In operation of a dataform reader illumination of a target area (210) is turned on before exposure of the first line of sensor elements (222A), each line of sensor elements is exposed by reflected illumination in an exposure period which overlaps with the exposure period of one or more other lines, and illumination is then turned off (228). Using a CMOS construction, for example, the level of image signals read from one line of sensor elements is referred to a look-up table to determine an appropriate exposure period for a subsequent line or lines of elements of an array. This process is repeated to achieve exposure periods adjusted for localized exposure conditions for each successive line or subset of lines of sensor elements.

Patent CA-2184312-A1 (CA)
Inventor: DOSMANN ANDREW
IPC: G01N33/52
Filed: 1996-08-28
Abstract: A diffused light reflectance readhead is disclosed. The readhead employs an improved light emitting diode (LED) providing a more strongly collimated beam of light around a beam axis onto a reagent test pad. The reagent test pad is supported on a strip guide at an angle .alpha. of 5 degrees with respect to the perpendicular of the beam axis. It has been discovered that when .alpha. is between 3 and 8 degrees that specular reflection is dramatically reduced in relation to the small reduction in reflected light received by a sensor. The diffuse reflected light travels to the sensor by passing through a staircase optical baffle at an angle of 45 degrees to the perpendicular of the beam axis. The sensor converts the optical signal into an electrical one for processing and analysis. One embodiment of the present invention can detect the presence of glucose in a blood sample.

Title: Use of co2 absorbant for stabilization of dried alkaline reagent in creatinine assay
Inventor: CHU AMY H
IPC: G01N33/52
Filed: 1996-08-28
Abstract: Disclosed is an improvement to the method for the detection of creatinine in which creatinine, in aqueous solution, is contacted with a dry reagent system of an indicator for creatinine. The assay is carried out at a pH above about 11.5 which is maintained by an alkaline material. The improvement involves packaging the reagent system with a material capable of absorbing CO2 and at least some ambient water vapor. This inhibits the formation of carbonic acid thereby reducing the neutralization of the alkaline reagent system during storage to increase the shelf life and decrease the variability of the system.

Title: A modulator/demodulator arrangement for data transmission in a radio communication system
Inventor: VAN TOLEDO RENE CORNELIS HENDR
IPC: H04W88/02
Filed: 1995-07-18
Abstract: Known modulator/demodulator arrangements supply data originating from a data terminal, via transceiving means and via modulation/demodulation means, to a transceiver arrangement, like a mobile station or a cordless handset, via a connection which for example is formed by a coupling to microphone connections and loudspeaker connections associated with the transceiver arrangement, and control the transceiver arrangement for setting up a radio connection, via further transceiving means and via a further connection, which for example is formed by a coupling to the keyboard connections and the display connections associated with the transceiver arrangement. By providing the modulator/demodulator arrangement with switching means for activating a coupling present via one of both connections and de-activating a coupling present via the other one, the transceiver arrangement does not have to possess any knowledge about which of both connections is to be used. Due to this, an ordinary transceiver arrangement could be used, without complex adaptations being necessary.

Patent CA-2194235-A1 (CA)
Title: Platform unit
Inventor: KRAUSE GUENTHER
IPC: E04G1/15
Filed: 1995-05-24
Abstract: Platform units for scaffolding must be light and strong in design and be usable without any risk of accident. For a long service life, all their parts should therefore be included in any static analysis. High rigidity of the corner joints of the rectangular support frame of the platform unit, as well as the narrowest possible gaps between adjacent platform units are desirable. To this end, the invention uses a disposition of the mounting brackets (3) on the frame (1) which combines structural symmetry with the fact that the mounting brackets (3) are offset, thus allowing platform units to be assembled with only a narrow gap between them. In spite of their lightweight construction, the corner joints (E) of the support frame are resistant to distortion and any uncertainty due to the use of wooden planks (21) for the standing surface (2) is avoided by using a plank-holding frame (22) whose size is subject to calcultation.

Inventor: GALAS BOGDAN A
IPC: B65G67/22
Filed: 1997-01-30
Abstract: A method and apparatus for assisting in obtaining a complete filling of a moving container vehicle with a flowable load.  The apparatus comprises a baffle having an upper edge and a lower edge and a baffle positioning means.  The method provides that the baffle position means initially sets the baffle at an angle with the lower edge thereof just inside the forward end of the container to thereby constrict the flow of the material.  As the container is moved forward the baffle is also moved forward thereby providing less constriction to the flow and ultimately the baffle is moved to a position in which there is no constriction of the flow.
