Abstract: A receiver and associated method estimates a channel impulse response of the communications signal. A communications signal is received as a burst of transmitted symbols, including a known training sequence. The joint estimation of timing offset and initial channel impulse response is determined based on the cross-correlations of the known transmitted symbols and received communications signal. A constant modulus interference removal iteration is applied to improve the initial channel impulse estimation.

Abstract: Displaying a map on a wireless communications device includes steps of obtaining map data for rendering the map to be displayed on the wireless communications device, determining a rotation that, when applied to the map, will orient a selected path in a selected direction, such as a current direction of travel, generating a corrected rotation by applying a spherical correction factor, e.g. based on a current location, and rendering the map on a display of the wireless communications device by applying the corrected rotation. The spherical correction factor corrects for map distortions that occur at high latitudes for paths that are neither purely north-south or east-west. When such a path is rotated to face upward to show direction of travel, the path needs to be straightened by applying the spherical correction factor.
Abstract: Labels can be rendered on a map displayed on a wireless communications device by using pre-rendered characters. The pre-rendered characters can be pre-rotated to one of a number of angular orientations and stored as a variable transparency bitmap for rapid overlaying on the map. The bitmap can include an array or grid of characters wherein each row has a unique orientation, for example, ranging from zero to ninety degrees. Rotations of 90 to 360 degrees can then be achieved by reflecting the characters about vertical or horizontal axes. Overlaying pre-rotated characters is more computationally efficient than computing rotations for each character when rendering the label.
Abstract: A method of stitching converging path segments to aesthetically label Y-intersections, path bifurcations or splits in roads or the like entails determining which pair of adjacent path segments subtend the largest angle. The path segments subtending the largest angle are reconstructed (stitched together) and a single instance of the label is then rendered along the reconstructed path. Although this stitching can be performed on the client device, pre-stitching server-side is even more efficient in terms of economizing over-the-air bandwidth and onboard processing resources.
Abstract: A method of displaying a map on a wireless communications device includes obtaining map data for rendering the map to be displayed on the wireless communications device, the map data including label data for rendering labels on the map. The device generates a collision-avoidance array representative of the map to be rendered for testing potential label positions prior to actually rendering the labels on the map. The collision-avoidance array is populated by provisionally designating, for each successive label to be rendered, a label space in the collision-avoidance array that corresponds to a map space that is to be occupied by the label on the map. The device then determines whether each successive label to be rendered collides in the collision-avoidance array with any previously designated label spaces. If no collision exists for a given label, the label can be rendered on the map.

Abstract: In displaying a map on a wireless communications device, a method is provided that resolves labelling of sharp curves. The method entails a determination of whether a curvature of a map element associated with the map feature exceeds a predetermined threshold (e.g. whether a rate of change in slope of a path or the change in angular orientation of each successive character in the label exceeds a threshold that is a function of zoom level. If the curvature exceeds the threshold, the label is rendered on the map in a new map location that avoids the map location where the curvature exceeds the threshold.
Abstract: Displaying a map on a wireless communications device includes downloading map data from which the map is to be rendered, rendering portions of the map for which the map data has been fully downloaded, and then graphically overlaying on a portion of the map for which the map data has not yet been fully downloaded a graphical indication, such as hatching, crosshatching or shading, to indicate that further map data is being downloaded. This hatching, crosshatching, shading, or writing informs the user that further map data is being downloaded and that not all of the map features have been rendered yet.

Abstract: A method of displaying a map on a wireless communications device includes steps of obtaining map data for rendering the map to be displayed on the wireless communications device, generating corrected map data by applying a spherical correction factor to the obtained map data, and rendering the corrected map data to display the map on a display of the wireless communications device. The spherical correction factor corrects for map distortions that occur at northerly (or southerly) latitudes. Since the spherical correction factor is a simple correction to a 3×3 transformation matrix, this spherical correction can be easily applied without taxing the CPU limitations of small handheld devices.

Abstract: A key server (320) based communication system (310) wherewith communicating parties, originators (312) and recipients (314), exchange encrypted communications (324). An originator requests or provides a key (330) to the key server, optionally with an assertion (322) from an authentication authority (318). Based on attributes (326) from the originator or elsewhere, the key server sets controlling events (340) for the communication. The originator encrypts and sends the communication to one or more recipients. A recipient may or may not request the key to decrypt the message. Positive events (342) are determined based on the controlling events and when and how many such requests occur. Negative events (344) are determined based on the absence of any requests or all requests being untimely.
Abstract: A server find process by which a user enters a search term for a document attachment into his/her mobile communication device. If no occurrences of the term are found on the device, the device then prompts the user to initiate a server side search. If the user accepts, then the server searches the document attachment and returns the first section of text that contains the search term to the device for viewing by the user. This process can then be repeated until the server find feature reports that no further instances of the search string have been found on the server.

Abstract: Home network name displaying methods and apparatus for multiple home networks are disclosed. A mobile station scans to receive a plurality of Mobile Country Code (MCC) and Mobile Network Code (MNC) pairs corresponding to a plurality of communication networks within a coverage area. The mobile station selects and registers with a communication network associated with one of the received MCC and MNC pairs for communication. After the network is selected, the received MCC and MNC pair is compared with a plurality of home network MCC and MNC pairs which are associated with a single home network display name. Based on identifying a match between the received MCC and MNC pair and any one of the home network MCC and MNC pairs, the home network display name is visually displayed in a display of the mobile station. If no match exists, an alternate name is selected for display.
