Abstract: An apparatus and method for receiving time skewed data from a parallel data bus. A data transfer on the parallel data bus is preceded by a start-of-cell delimiter consisting of a predetermined sequence of pulses on each of the data signals. The data is received from the bus by receive logic employing a local clock. Sampling logic is used to sample each of the data signals received from the bus at a rate which is higher than the local clock rate. Sample registers store a plurality of samples of corresponding data signals, the number of samples stored being large enough to store at least some of the pulses constituting the start-of cell delimiter. Start-of-cell detect and center select logic is used for determining that a start-of cell delimiter is stored in each of the sample registers, and for determining which of the samples stored in each of the sample registers represents the approximate center sample of one of the pulses of the start-of-cell delimiter. These center samples correspond to the data signals on the bus, but are de-skewed and synchronous with the local clock.

Filed: 2000-06-21
Granted: 2004-11-30
Abstract: This invention relates to a method for producing a product which exhibits (a) a low level of emissivity and (b) a high level of moisture vapor permeability, and which enables trapped excess moisture to be transported from the product to the surrounding atmosphere while maintaining its effective radiant barrier properties. The product is an underlying substrate, having a pair of outer major surfaces and a radiant barrier material adhered to at least one of the pair of outer major surfaces of the underlying substrate with an adhesive material to form a radiant barrier material covered substrate. A plurality of apertures are formed in the radiant barrier material covered substrate. These apertures extend substantially completely through both the radiant barrier material and the adhesive material thereby forming substantially completely open moisture vapor flow channels which create a high level of moisture vapor permeability through the radiant barrier material and the adhesive material. In this way, a substantial amount of trapped excess moisture can pass from the underlying substrate into the surrounding atmosphere to avoid unwanted degradation of the underlying substrate, while maintaining the low level of emissivity of the product.

Title: Mobile facility and process for mining oil bearing materialsand recovering an oil-enriched product therefrom
Inventor: KAETHLER HARRY
IPC: C10G1/04
Filed: 2001-01-24
Granted: 2002-02-26
Abstract: The mobile facility and the process are used for mining oil bearing tar materials, such as tar sand, and recovering an oil-enriched product therefrom. Oil bearing materials are mined using a mining head and processed directly into the mobi le facility where an optimum amount of oil-enriched product is removed therefro m. Unlike conventional technologies, only a relatively small amount of solvent is used and most of it is recycled back into the process. The process does not need a tailings pond since the tailings are substantially dewatered at the end of t he process. Further, the tailings are deposited in an adjacent area once they come out of the mobile facility. This significantly reduces the material handling  and transport undertaking, thereby allowing the process and the mobile facility to be operated at substantially lower costs compared to conventional technologies.

Abstract: A technique to switch between upper and lowercase alphabetic characters in a wireless communication device measures the period of time in which a numeric key is held in the depressed position by the user.      If a numeric key is pressed by the user for a period of time less than a predetermined threshold time (212), the selected alphabetic character is displayed in a default character case. If the selected numeric key is held in the depressed position for a period of time exceeding the predetermined threshold period, the character case is altered and the altered alphabetic character is displayed for the user (214). The user selects the desired alphabetic character by activating a selected numeric key one or more times corresponding to the desired alphabetic letter. If the selected numeric key is held in the depressed position for a period of time exceeding the threshold period during any of the button depressions (212), the system automatically changes to the altered alphabetic character case (214). The alphabetic character case is controlled on a character by character basis such that entry of a new alphabetic character uses the default character case unless the selected numeric key is again held in the depressed position for a period of time exceeding the predetermined threshold.
