Title: Digital mobile communications clock extractor
Inventor: GREENWOOD MARTIN
IPC: H04M1/72505
Filed: 1989-12-13
Abstract: Digital mobile communications apparatus, such as a cordless telephone, having clock recovery to enable sampling of the input signal, comprises a reference signal generator (40, 42) which provides a reference signal to a phase error adder (44) operating on the basis of modulo-arithmetic in a feedback loop which also provides frequency tracking, the feedback loop having single point gain adjustment for bandwidth control of two digital integrators (51, 54 and 56) which are clocked at differing speeds. When enabled, the up/down counter 42 accumulates the one-bit quantized value of the phase error by either counting up or down. Single point gain adjustment is made within the up/down counter 51 by selecting the word width of the counter <IMAGE>

IPC: B41J13/20
Filed: 1989-12-29
Abstract: A paper bail is opened and closed during successive angular rotations of a platen by a camming arrangement comprising a wheel which is toothed over only part of its periphery. During printing the untoothed portion faces a driving gear fast with the platen, and the bail remains closed. …<??>When fresh paper is inserted, the print head carriage is traversed to one end of its travel, where it coacts with a lever which causes a latch (29) to release the partially toothed wheel (25) which wheel then becomes enmeshed with the drive (4). The wheel drives a cam (27) which effects bail movement. …<IMAGE>…

Title: Alarms for suitcases and the like
Inventor: HORNG MING-GIN
IPC: A45C13/24
Filed: 1991-10-10
Abstract: A handle-attachable suitcase alarm comprises a soft handle cover 1, a conduction strip 2, and an alarm means 3. The soft handle cover has A-electrode and B-electrode contact faces, and can be rolled around a suitcase handle with its two ends stuck to each other by two touch and close fasteners 11, 12 attached thereto. The conduction strip has its free end connected to the A-electrode contact face while its root is connected to the B-electrode contact face. Using a human hand as a conductor, the A-electrode and the B-electrode contact faces are electrically connected when the soft handle cover is gripped, and this generates a signal which is transmitted via the conduction strip to the alarm means. A conductive member may be installed on the soft handle cover (1) at one end across the two contact faces with an insulation pad under it to keep it from touching the contact faces at normal times. Such an arrangement is helpful for the connection of the two contact faces and is suitable for use in extremely dry areas where insulation might be influenced. <IMAGE>

Title: Optical apparatus for testing the oculomotor and pupillary systems of the eye
Inventor: WALDORF RONALD ALAN
IPC: A61B3/113
Filed: 1992-05-14
Abstract: A non-invasive apparatus for monitoring physiological responses for detecting the presence of drug impairment. The oculomotor and pupillary system is monitored and evaluated to detect the ingestion of drugs and the impairing effect or influence thereof. The horizontal, vertical, oblique and torsional eye movement, eye lid blink activity as well as the size and reactivity of the pupil are the primary data sources. An enclosed chamber surrounds each of the eyes of the subject, and thereby precludes the admission of ambient light. Within each chamber are disposed point sources of infrared radiation specifically oriented with respect to the subject's eye. An infrared sensitive video camera is positioned to minimize the effect of cosine compression within each chamber relative to the subject and is positioned with respect to the infrared radiation sources in order to provide maximum contrast between the pupil and iris of the eye. To detect movement of the eye in response to visible stimulus, a plurality of low intensity, visible light sources are disposed horizontally and vertically within each chamber. The sequential illumination of the visible light sources simulates eye movement while precluding pupil reaction thereto. The output of the video camera is processed concurrently with data responsive to other physiological responses to determine drug impairment.
