Patent CA-2038780-A1 (CA)
Inventor: CHRISTOPHER TODD J
IPC: H04N3/27
Filed: 1991-03-21
Abstract: Adjustment and maintenance of a phase relationship between a video signal (on 11) and a scan synchronizing signal (on 67) to assure proper horizontal centering is provided in a horizontal deflection system (40). A first phase locked loop generates a first timing signal (on 17) at a first frequency, synchronously with a horizontal synchronizing component in a video signal. A presettable counting circuit (in 56) operates synchronously with the first timing signal for dividing a clock signal to generate a second timing signal (on 61) at a second frequency. A second phase locked loop (62) generates a scan synchronizing signal (on 67) from the second timing signal. A microprocessor (74) may supply different numbers to a register (in 56), the output of the register being coupled to the presettable counting circuit. Different numbers (from 74) change the relative phase between the first and second timing signals by incremental steps. The microprocessor (74) monitors a video source selection switch to gate one of alternative video sources as a video and synchronizing signal output and adjusts the relative phase between the horizontal synchronizing component of the selected video source and a synchronous timing signal by a factor appropriate for the selected video source. A manually operable circuit (72) may be coupled in a feedback path of the second phase locked loop (62) for adjusting the relative phase between the second timing signal (on 61) and the scan synchronizing signal (on 67), over a range corresponding to an incremental step. <IMAGE>

Title: Automatic storage and retrieval apparatus
Inventor: STERNAD WILLIAM A
IPC: E04H6/12
Filed: 1991-05-23
Abstract: Storage and retrieval apparatus and method using pallets for storing vehicles and other loads. A number of storage levels aligned vertically are reached by a pair of lifts in shafts which bracket the levels. A transfer mechanism can push a pallet and automobile from either lift onto any level. Each level is always filled with pallets and sized to exactly hold an integral number of pallets.      When a pallet is pushed into a level from one lift the intermediate pallets are pushed laterally to the opposite lift, resulting in the farthest pallet being ejected onto the opposite lift located at the same level. Separate loading stations are provided on ground level for each lift.      An automobile can be driven on or off a pallet or a load placed on or off a pallet at the loading station. A loading station mechanism can move a pallet with a load to be stored from the loading station onto a lift. The lift transfer mechanism can transfer a pallet with a load being retrieved from the lift onto the loading station mechanism adjacent the lift, and the loading station mechanism can move the pallet from there to the loading station. A computer having input apparatus, input sensors, output apparatus and displays, utilizes a program to control and optimize the operation. Input identifiers for each automobile, or other load, and pallet are entered into the computer upon storage to permit ready retrieval.

Inventor: HAHNE ELLEN L
IPC: H04L12/40
Filed: 1991-09-05
Abstract: Bandwidth balancing is accomplished in Distributed-Queue Dual-Bus (DQDB) networks that handle multi-priority traffic by causing each node to throttle its own rate of transmission in accordance with the priority of the data that the node transmits. In accordance with one approach, each node limits its throughput to the product of a bandwidth balancing factor (which is a fraction that varries according to the priority level of data) and the unused bus capacity. When parcels of different priorities are received within each node, the parcels are processed in priority order. In accordance with another approach, all active parcels within a node are handled concurrently and receive some bandwidth. The throughput of each parcel in a node is limited to the product of the bandwidth balancing factor and the unused bus capacity. In accordance with still another approach, each traffic parcel limits its throughput to the product of the bandwidth balancing factor and the bus capacity unused by parcels of equal or higher priority. This scheme allocates bandwidth first to the higher-priority parcels, then allocates the leftovers to the lower-priority parcels. Lower-priority parcels have no effect on the steady-state throughputs of higher-priority parcels.

Title: Mechanism for accessing digitized image database to provide iteratively improved display resolution
Inventor: CAINE HOLDEN R
IPC: G09G5/00
Filed: 1991-09-12
Abstract: The "viewing delay" encountered when accessing a digital image from a relatively high resolution database stored using a digital storage device with a relatively slow transfer rate, such as a compact disc, is substantially reduced by a readout and display control mechanism that rapidly provides the viewer with an initially relatively low resolution image and thereafter increases the resolution of the displayed image. By presenting the viewer with such a "quick-view" low resolution image, the present invention enables the viewer to determine whether the image being displayed is of interest, so that the viewer has the immediate option of calling up another stored image or permitting the currently displayed low resolution image to be iteratively enhanced, so as to obtain a higher resolution image.
