Filed: 2000-09-07
Granted: 2004-05-01
Abstract: The inventive optical sheet to be used for a back light unit of a liquid crystal display having at least a lamp and a light guiding plate has the following structure. The optical sheet is constituted by a lower base portion and an upper fitting portion which are fitted each other in a vertical direction with less margin, and the base portion and the fitting portion are formed of materials having different refractive indices. The base portion is provided with a large number of triangular portions having a triangular sectional shape in parallel, the triangular portion having a first side surface positioned on the left side and a second side surface positioned on the right side. Moreover, the first side surface of the triangular portion has an angle which is equal to or greater than an angle formed between a direction taking a peak of a ray refracted and incident on an inside of the base portion through a light guiding plate and the transverse direction. Furthermore, a direction taking a peak of a ray refracted and incident on the fitting portion through the second side surface of the base portion is caused to more closely approach an upward direction than a direction taking a peak of a ray transmitted to the second side surface through the inside of the base portion.

Title: Method for driving display, driving circuit therefor, display and electronic apparatus
Inventor: YATABE SATOSHI
IPC: G09G3/20
Filed: 2000-11-18
Granted: 2002-07-21
Abstract: In order to reduce power consumption in halftone display in the present invention, each of a plurality of scanning lines is selected for one horizontal scanning period, each horizontal scanning period is divided into first and second half periods, and a selection voltage is applied for one half period. In case of halftone display, the selection voltage is applied for a second half period to the odd scanning lines and applied for a first half period to the even scanning lines. To pixels located along the selected scanning line, a drive voltage is applied for a part of a period corresponding to the gradation when the selection voltage is applied through a relevant data line, and a non-drive voltage is applied for the remaining part thereof when the selection voltage is applied through a relevant data line. Since only two voltage switchings for one horizontal scanning period 1H are needed for a data signal Xi for halftone display, power consumption required for voltage switching is reduced.

Title: User interface management through view depth
Inventor: BROWN FRANCES C
IPC: G06F19/00
Filed: 2000-12-08
Granted: 2002-07-11
Abstract: Several different methods for presenting (e.g., displaying) a hierarchical structure are presented. The hierarchical structure includes multiple elements, and defines hierarchical relationships between the elements. The hierarchical structure may be embodied within an electronic document such as a web document, an interactive application program, or a map divided into sections. Each element has a ""presentation property"" which may be a value or a function. A single one of the elements has ""focus"" (e.g., in accordance with the coding of the document by an author, by default, etc.). A ""view depth"" method includes forming a model (e.g., a tree structure) of the hierarchical structure. The model includes multiple levels ranked with respect to one another, multiple nodes representing elements, and at least one branch. A root node occupies a highest level in the hierarchical structure. A given branch connects a first node in a first level to a second node in a level directly below the first level. Each branch represents a hierarchical relationship between the connected nodes. A ""focus node"" represents the element receiving focus. The presentation property of each element represented by a node in the same level of the model as the focus node is presented. The presentation property of each element represented by a node in a first number of levels higher than the level of the focus node, and/or a second number of levels lower than the level of the focus node, may also be presented.

Title: Application operation in an internet compatible bi-directional communication system
Inventor: BROERMAN KEITH ROBERT
IPC: H04N7/10
Filed: 2000-12-26
Granted: 2002-10-11
Abstract: A system enables a bi-directional communication device such as a modem to facilitate local communication between the modem and an attached PC as well as to enable the PC to conduct concurrent Internet and local communication. A bi-directional communication system employs a method for seamlessly communicating packetized data between different networks using hierarchical layers of communication protocols (e.g. including Internet protocol (IP) and media access control (MAC) layers). The method involves comparing a received IP packet destination address in a first protocol layer with a predetermined IP address to determine if there is an address match. Upon such an address match, a payload of the received IP packet is redirected from an Internet network to a local network (e.g. an Ethernet, HPNA or USB network) by substituting a second protocol layer address for a received second protocol layer address (e.g. a MAC address). In another feature, a second Application (e.g.peripheral control) is initiated to operate concurrently with a first application (e.g. web surfing) in response to receiving the redirected payload data.

Title: Method and apparatus for aligning a waveguide to a device
Inventor: STANKUS JOHN J
IPC: H01L31/0232
Filed: 2001-01-10
Granted: 2003-02-21
Abstract: An apparatus which aligns a fiber core to a detector on an integrated circuit has a transmission material connecting them which steers the light provided through the fiber core to the detector even in the case of misalignment. The transmission material chosen has a characteristic of being able to have the spatial distribution of its index of refraction altered by electrical means. In this case, an electric field is applied in the area surrounding the path from the fiber core to the detector. Thus, even if the fiber core is not aligned to the detector, the light will be directed from the fiber core to the detector due to the path being surrounded by a lower index of refraction than the path itself. Thus, there is very little loss due to misalignment between the fiber core and the detector.

Title: Method of, and receiver for, detecting the presence of data
Inventor: PORCINO DOMENICO GIUSEPPE
IPC: H04B1/16
Filed: 2001-02-08
Granted: 2003-01-21
Abstract: A method of, and a receiver for, detecting the presence of digitally modulated data signals in which the receiver is periodically energised to detect the presence of the signals. The received signals/noise are converted using a quadrature frequency translation stage (16, 17, 18) into a complex signal which after differential decoding (28) contain n samples for each transmitted bit. A running sum of successive groups of m samples, where m < n, is obtained and an absolute value (Xi) of each group is derived. A weighting value (Wi) is selected by comparing each absolute value with predetermined statistics of expected values and the weighting value selected is multiplied by the associated absolute value to produce a product (S). The product is compared in a comparator (56) with a further threshold level (58) to derive an indication of the presence of data in the received signals. If the indication is negative the receiver is powered down to save power.
