Patent CA-2094880-A1 (CA)
Title: File difference engine
Inventor: SQUIBB MARK
IPC: H04L29/08
Filed: 1993-04-26
Abstract: Inversion maintains duplicate files in safe places. A scan computer program creates a token table of a file. The token table reflects the indices of successive segments of the file and the exclusiveor (XR) and cyclic redundancy check (CRC) products of the characters in each segment. An updated file is compared to the earlier file by comparing the XR and CRC products of segments in the updated file to the XR and CRC products in the token table. On detecting matching products for identical segments, the next segments are compared. On mismatch, the segment (window) for the updated file is bumped one character and new XR and CRC products generated and compared. The indices of the token table and the offsets from the start of the file of the first characters of the updated file matching segments are set forth in a match table. Next the updated file is scrolled through for the non-matching information determined by acting on the indices and offsets of the match table to form the transition table which is the match table and the updated file non-matching information. The transition table contains the delta information which may be sent to another location having a copy of the earlier file thereat: the whole updated file need not be sent there. A reconstruction program at the location looks at the transition table to determine where to get the characters for the copy of the updated file it is creating.

Title: Resolution Transforming Raster-Based Imaging System
Inventor: FRAZIER ALLEN L
IPC: G06T3/40
Filed: 1991-11-06
Abstract: A conventional display device, such as a marking engine for a laser printer or digital copier, having a nominal resolution (where the energy source for the display device can be selectively activated) and a predetermined threshold level for producing output image dots,  (see Fig. 5), is modified to a different (higher or lower) resolution or modified to produce output dots along axes (7, 9 and 11 in Fig. 10) different from the axes (3,5) of the display device (such as for producing halftone screens on angles), by using different resolution input data, and by selectively activating the energy source to produce overlap areas (see Fig. 10) that exceed the device threshold and thereby produce dots (17) at positions that are not on the normal resolution positions of the device (lines 3 and 5).  Such threshold exceeding overlap areas may be achieved by activating the marking engine's energy source at a plurality of positions, with the energy at some positions being selectively below the threshold level for producing an output dot, but with the combined energy at the desired dot positions being above the threshold level to produce the desired dot (see Figs 6, 7 and 8).

Abstract: SLEEVE PUPPET                     Abstract of the Disclosure A garment having an amusement device in the form of a puppet being integrally a part thereof and attached to the sleeves of the garment. The puppet is formed from the sleeve of a garment having two distinct layers of material which are attached at one end. A first layer extends into a second layer wherein the first layer is attached to the second layer at the end of the sleeve through which the hand extends. The interior end of the second inner layer is substantially unattached to the outer layer. Because of the substantially unattached interior end, an upper and a lower cavity is formed within the sleeve between the two layers of material. Accordingly, the fingers of the hand may be placed in the upper and lower cavities for manipulating the end of the sleeve and forming a puppet. When desired, the inside layer can be folded outwardly to form a cuff such that the puppet is hidden from view. Upon unfolding the cuff, the puppet is exposed. Ornamental items which represent facial features of a puppet, including hair, eyes and nose are applied to the outer layer of material.  In the unfolded position, the cavities can be moved in an upward and downward manner such that the inner layer of material represents the mouth and the outer layer of material represents the face of the puppet. Upon conclusion of playing with the puppet, the inner layer may be folded outwardly over the ornamental items to form the cuff and thereby hide the puppet from view.

Title: Method and apparatus for heart transplant monitoring and analog telemetry calibration
Inventor: THOMPSON DAVID L
IPC: A61N1/372
Filed: 1993-04-12
Abstract: A cardiac pacemaker with an analog telemetry system. A  calibration circuit within the pacemaker is adapted to provide a reference signal of known character to the pacemaker's telemetry system.  The reference signal is transmitted across the telemetry link as if it were an actual cardiac signal, and received by an external programmer. Since the reference signal has known, predetermined qualities, the programmer can automatically calibrate and scale the telemetry signal from the pacemaker, thereby increasing the accuracy of the telemetry channel. The increased accuracy is particularly useful in assessing rejection of a transplanted heart, which is known to be associated with a 15 % decline in the peak R-wave amplitude of the cardiac signal.

Patent CA-2124921-A1 (CA)
Inventor: HART JAMES E
IPC: B60T13/40
Filed: 1994-06-01
Abstract: A relay valve device for a relayed type brake system in which the compressed air of the auxiliary reservoir is connected to an equalizing reservoir instead of directly to the brake cylinder, as in a conventional system. Since the equalizing reservoir volume is fixed, as compared to the brake cylinder volume which varies with piston displacement, the equalizing reservoir volume must be greater than the final brake cylinder volume in order to obtain a full equalization pressure that matches the full service application pressure in a conventional brake system. The relay valve device employs a control piston that is subject opposingly to the equalizing reservoir pressure and the effective brake cylinder pressure delivered by the relay valve device. A differential pressure area of the control piston is selected in accordance with the volumetric ratio between the auxiliary and equalizing reservoirs so that the buildup of brake pressure substantially matches the conventional system partial application pressures, as well as full equalization pressure. A bias spring acts on the control piston to delay its actuation so as to cause the relayed pressure buildup to correspond in time to the conventional system brake pressure buildup.
