Title: Apparatus and method for preventing unauthorized circumvention of television program blocking function
Inventor: TAM TONY T
IPC: H04H20/76
Filed: 1999-10-08
Abstract: A method and apparatus for preventing unauthorized circumvention of blocking of television programs. The system of the present invention prevents an unauthorized person from circumventing the VChip blocking of a specific show or channel through tuning with the cable box. A controller monitors the vertical synchronization (VSyncs) of the video signal coming into the TV  (102). If a video interrupt is identified by the controller without the TV  sending an IR command to the cable box, the controller redials the cable box to the channel it was on before detecting the video interrupt. This hinders an unauthorized person from working around VChip blocking functions.

Title: Method and apparatus for batching-out items such as poultry pieces
Inventor: JENSEN SVEND BAEKHOJ
IPC: G01G19/387

Abstract: A batcher apparatus comprising a weighing station (4) for arriving items and a sorting-out station (6) with transfer means for selectively transferring the weighed items to a plurality of receiver stations (18, 18', 18''), controlled by a control unit (14) with the purpose of building up weight determined item batches in the respective receiver stations (18, 18', 18''). According to the invention two or more receiver stations may be used as substations (18', 18'') being allocated items weightwise belonging to the same batch (26), whereby it is possible to allocate to each batch item, which are selected not only based on their weight, but additionally based on other criteria such as type of item in connection with co-batching of different types of poultry parts to be batched separately in subbatches which are then merged into the full batch.  Also, items may be allocated to one substation or another in order to thereafter be acted upon in a specific manner, e.g. for some items to be turned or marked.
Patent CA-2348282-A1 (CA)
Title: Systems and methods for modifying ice adhesion strength
Inventor: PETRENKO VICTOR
IPC: E01D19/00
Filed: 1999-10-26
Abstract: The invention includes system for modifying ice adhesion strength of ice adhered to an object. The system includes an electrode that is electrically insulated from the object and a DC source, e.g., a battery, coupled to the object and the electrode. The source generates a DC bias to an interface between the ice and the object when the ice completes the circuit. The object is conductive or is doped as a semiconductor so that the DC bias applies a voltage to the interface which modifies the ice adhesion strength selectively as compared to the ice adhesion strength with substantially zero bias voltage at the interface. The strength can be increased or decreased relative to its static state (i.e., the state without applied voltage). In this manner, ice such as ice on an aircraft wing can be removed with less work. The system preferably includes an electrically insulating material disposed between the object and the electrode; the insulating material is substantially conformal to the object and the electrode. In most applications, the electrode includes a grid electrode shaped to conform to a surface of the object and each point of the grid electrode is in electrical contact with the source. Accordingly, a grid insulator is generally disposed between the object and the grid electrode. The invention of one embodiment incorporates porous materials to selectively dope the ice on a surface; and the invention of another embodiment incorporates self assembling monolayers to reduce the strength of hydrogen bonding between ice and metals. In one embodiment, the invention provides for coating a power line that changes properties with temperature such that the coating melts snow in freezing conditions.

IPC: G06T1/00
Filed: 1999-11-12
Abstract: An apparatus and method for acquiring an image of a patterned object such as a fingerprint including a light refracting device, a focusing lens, and a light source. The light refracting device can, for example, be a prism and includes an imaging surface, a light receiving surface and a viewing surface. Incident light from the light source is projected through the light receiving surface and reflected off a surface other than the imaging surface. This reflected light is then projected onto the imaging surface to create an image of the patterned object from substantially all scattered light through the viewing surface. The lens is placed adjacent to the viewing surface to focus the light on an image sensor.

Patent CA-2374891-A1 (CA)
Inventor: SASAKI HIDESHI
IPC: A01D34/90
Filed: 2002-03-06
Abstract: In a plant cutter apparatus, a handling rod includes an outer pipe portion, an inner pipe portion and three radial stay portions interconnecting the outer and inner pipe portions. The three stay portions are arranged, about an axial centerline of the rod, at non-equal angular intervals in such a manner that angles formed between the three stay portions differ from each other. Thus, the rod has a cross-sectional configuration asymmetric about the axial centerline. Geometric moment of inertia of the thus-constructed handling rod takes different values in all angular positions about the axial centerline, and thus the inherent vibrating frequency of the rod also takes different values in all the angular positions. Consequently, the rod's inherent vibrating frequency coincides with a frequency of vibrations transmitted from a drive source unit in only one of the angular positions, so that resonant vibrations of the handling rod can be avoided easily.

Abstract: A quilting system (10) that includes a multiple needle quilting machine (11) is provided with batch processing capability by the addition of a panel cutter (30) in-line with and downstream of the quilting machine (11). The panel cutter (30) is equipped with a programmed controller (29) that is loaded with batch information for the production, on the quilting machine, of a plurality of quilts by stitching patterns on a multilayered web of fabric (12). The batch information includes information of a number of quilts to be quilted as well as the patterns to be quilted on each quilt and the composition of the material on which the patterns are tobe quilted. Information is derived by the panel cutter controller (29) from sensors (36) on the panel cutter (30), which information is used to control the quilting machine (11) by adjusting the length of quilted material from the quilter. The panel cutter controller (29) may also operate the quilter to adjust for shrinkage in web length caused by the quilting, and to synchronize splices in the web between different material layer combinations for different quilts of the series to be quilted.
