Title: Video enhancement system
Inventor: FOK STANLEY
IPC: H04N1/409
Filed: 2007-05-24
Abstract: Systems and methods are provided for enhancing the image quality of video. One or more filters 12 may be used to filter a received video signal 18 to generate vertical, horizontal and diagonal filtered outputs. Amplification components 14 may be used to apply separate gains to each of the filtered outputs to generate vertical, horizontal and diagonal enhancement signals. Summation components 16 may be used to combine the vertical, horizontal and diagonal enhancement signals with the video signal to generate an enhanced video signal 20. Gain signals may be generated by use of an RGB to Y converter 72 to convert an RGB signal 86 to a simplified greyscale. A mean absolute measure calculation 74 may be performed on each greyscale pixel to calculate a contrast measure, and the use of edge 76 and texture 78 look up tables may be used to classify the pixels as edge or texture pixels. Summation components 80, 82 apply edge and texture enhancement signals to the pixels to generate vertical, horizontal and diagonal edge 88 and texture 90 enhancement signals. The enhancement signals may be combined by summation component 84 to generate the enhancement gain signals.

Title: Performing a function on an off premises telecommunication terminal associated with a PBX
Inventor: ABRAMSON SANDRA R
IPC: H04M1/725
Filed: 2007-06-01
Abstract: A technique is disclosed that provides a conduit for enabling a private branch exchange (PBX), or other data-processing system, to initiate the performance of a function on a cellular telephone or other off-premises telecommunications terminal that is affiliated with the exchange. The conduit comprises a client application that resides on the off-premises terminal that observes the calling party identifier of all incoming calls. When the private branch exchange desires to initiate a function on the terminal, the exchange dials the terminal and postpends dialed digits by using dual tone multi-frequency signaling, where the dialed digits identify the particular function call and the arguments of the function. When the client application on the telecommunications terminal determines that the value of the calling party identifier is from the private branch exchange of the illustrative embodiment, the application looks for the postpended dialed digits and, upon finding them, initiates the function that corresponds to them.

Title: Wet razor with opposing blades
Inventor: DELANEY COLIN GEORGE
IPC: B26B21/16
Filed: 2007-06-12
Abstract: The razor comprises two blades 1, 2 set horizontally one above the other where the top blade 1 faces downwards and the bottom blade 2 faces upwards. The fact that the blades face each other enables the user to chose either downward shaving strokes, upward shaving strokes, up and down shaving strokes or side to side shaving strokes, while the razor is held in a single upright position by the handle 3, 4 allowing shaving in all directions. The razor gives a faster, closer, cleaner, and more convenient and precise shave without turning the razor upside down.

Title: I.c engine air hybrid vehicle
Inventor: MA THOMAS TSOI HEI
IPC: B60K6/12
Filed: 2008-02-28
Abstract: An air hybrid vehicle is powered by a multi-cylinder internal combustion engine with at least one intake valve 12 per cylinder and a non-return valve 32 located in the intake port for blocking reverse flow. An auxiliary chamber 30 is provided in the intake port between the intake valve 12 and the non-return valve 32 and is connected via a self-sealing valve 34 to a separate air storage tank 36 common to all the cylinders of the engine. The engine has a variable valve engine braking device 40 operable to produce an engine braking cycle during which the intake valve 12 is allowed to open and close normally during the intake stroke but prevented from closing completely during the rest of the engine cycle. During strong engine braking of the vehicle, fuel supply is shut off while the variable valve engine braking device 40 is activated and compressed air is forced past the unclosed gap of the intake valve 12 into the auxiliary chamber 30 and through to the air storage tank 36. During driving of the vehicle, the variable valve engine braking device 40 is deactivated, fuel supply is restored and compressed air from the air storage tank 36 is delivered into the intake manifold 50 for driving the engine as well as supporting combustion in the engine.

Title: Improvements in and relating to inflatable flotation devices
IPC: B63C9/19
Filed: 1934-04-04
Abstract: 429,540. Collapsable craft. KIDDE & CO., Inc., W., 60, West Street, Bloomfield, New Jersey, U.S.A. April 4, 1935, No. 10175. Convention date, April 8, 1933. [Class 113 (i)] [See also Groups VII and XXI] Inflatable flotation devices such as life-vests or belts, lifeboats or rafts have two or more separate compartments which are simultaneously inflated from a pressure - source through a manifold which is provided with valves for preventing a reverse flow of the pressure medium. The manifold 10 is in communication with the compartments of 2, 3 of the inflatable flotation device by way of the ducts 60 and with the pressure source 8 by way of the centrally-disposed duct 35. On fracture of the sealing-disc 18 by operating the handle 27, pressure gas presses back the spring-loaded valves 38 and inflates the chambers until the pressure in the system is equalized when the valves close. The chambers may be deflated by unscrewing endmembers 53 and pressing-back the valves 38. In another form applied to the inflation of a life-saving jacket, the rotation of a handle 93, Fig. 8, operates a cam 88 which presses forward a pin 84 to fracture a disc 80 and then in turn presses the spring-loaded valve 79 off its seat causing the rupture of a diaphragm closing the mouth of the gas-cylinder 64. Pressure fluid then flows past non-return valves in tubes 69, 70 to inflate the compartments of the jacket.

The strip may be held in engagement with the pins by means of the slotted guides 75 described in the above-mentioned Specification. The chains may be arranged to pass over three sprockets, one of these being spring-urged to tighten the chain. As applied to a typewriter, endless chains 33, Fig. 10, having pins 32 for engaging the strip 21 are arranged on sprocketwheels above the platen 100. Alternatively, the chains may pass around sprocket-wheels arranged above and on the platen.
