Abstract:
This invention relates generally to films made from crystalline polypropylene polymers. Specifically, this invention relates to films comprising crystalline polypropylene polymer compositions containing both propylene homopolymers and propylene copolymers. The compositions are prepared using metallocene catalyst systems comprising at least two metallocenes in a polymerization process that involves the sequential or parallel polymerization of propylene homopolymers and copolymers using propylene with a small amount of comonomer, preferably ethylene. The resulting polymers are excellent for use in the production of biaxially oriented films. Films prepared with these propylene polymers have a significantly broader processability range and can be evenly stretched at lower temperature compared to films prepared from traditional polypropylene polymers.

A dynamically reconfigurable antenna system is disclosed which may be configured with low cost discrete analog components. Particularly, the antenna elements, phase shifters, and beam forming network of the current smart antenna system are configured from RF transmission lines, RF couplers and RF switches in a system which is able to dynamically reconfigure its beam forming signals to point in a direction of greatest signal strength. The smart antenna system may be configured on portable devices to accomplish greater signal reception and transmission when used in a wireless network.
Abstract:
The present invention provides an optical scanner that adjusts the image-induced voltage by controlling the exposure time of the sensors. The optical scanner comprises a scanning module comprising a plurality of color detectors for detecting light of different colors when scanning a document to generate corresponding electric charge, a cathode-ray tube for providing light to the document, a power supply for supplying power to the cathode-ray tube, and a control circuit for controlling operations of the optical scanner and the power supply. The control circuit controls an exposure time of each of the color detectors according to the sensitivity of the color detector to its corresponding color of light so that the amount of electric charge generated by each of the color detectors during each exposure is controlled and properly scaled.
Abstract:
An improved scanner with automatic edge detection capable of quickly, accurately, and readily detecting the edges of a document or an object to be scanned. Said scanner with automatic edge detection comprises a main body, a scanning module, and an edge detector. The main body comprises a flat glass platform for supporting an object. The scanning module is installed inside the main body for scanning the image of an object placed on the flat glass platform of the scanner. The edge detector is located inside the main body to detect the edges of the object, thereby determining the size of the object before scanning. The scanner according to the present invention is capable of obtaining the correct size of the object being scanned without restricting the size of the object to match any of the fixed paper sizes in order for such scanner function as auto zooming to proceed successfully. In addition, through a microprocessor and a properly embedded computer program of a disclosed art, the scanner according to the present invention is capable of auto zooming on the scanned object without the assistance of a computer and a monitor.
Abstract:
The invention relates to an optical scanner for saving power. The optical scanner comprises a scanning module for scanning a document to generate corresponding image signals, a cold cathode ray tube for supplying lights to the document when scanning the document, a power source for supplying electric power to the cold cathode ray tube, and a control circuit for controlling operations of the scanner. When the scanning module is in an idle state, the control circuit controls the active period of each of the power source's duty cycles to reduce the electric power supplied to the cold cathode ray tube so that the cold cathode ray tube can be maintained in a warm state and the startup time for warming the cold cathode ray tube to scan the document is reduced.
Abstract:
An optical sensor switch system is used to effect a selection function of a scanner. The depressed switch for a selected function changes the light intensity incident on the pixels of a light sensitive panel in two steps. This change in light intensity activates the operation of the particular function. The change in light intensity is effected by shuttering the light from a source to the pixels. The pixels of the panel are divided into different sections, each designated to a particular function for the scanner.
Abstract:
A user interface having a plurality of user interface elements for marking, finding, organizing, and processing data stored in a computer system. Each element typically has an appearance which is related to the data or function the element is designed to represent or perform. The elements may simply mark data within the document, or may be programmed to cause the computer to perform some function in association with the marked data. Methods of marking data and searching the memory for marked data by use of switches or buttons is disclosed. Further, useful elements for systems such as computerized camera systems, portable multimedia systems, and remote controls are also described. Some of the user interface elements of the present invention may have an appearance and/or functionality dependent upon the context in which the element is used, and/or dependent upon the user's identity. Methods for arranging the elements in stacks, and for providing for automatic application of elements to captured image data are also disclosed.
Abstract:
A vehicle security system with anti-robbery function which has a mainframe including a software stored in a CPU and preset code recorded in a permanent memory unit. A key receiving means is electrically connected to the mainframe and a contact-type relief key also provided with a corresponding code which must match the preset code in the permanent memory unit to start the engine of a vehicle. The key receiving means is provided with a button and at least one relay is housed in the mainframe. Once the button is pressed, the security system enters an anti-robbery mode, and after a preset period of time, the CPU will make the horn of the vehicle honk and the head light and direction indicating lights flash continuously. After the engine is stopped, the CPU uses the relay or relays to make the engine starting circuit inoperative so as to further control the power-on, engine starting, ignition and oil supply circuitries of the vehicle not to function, making the security system operated in a more secure and practical manner.
