Title: Manhole adjusting extension member
Inventor: WIEDRICH DWIGHT G
IPC: E02D29/14
Filed: 1997-05-29
Granted: 2001-10-30
Abstract: A molded plastic extension member for use in increasing the height of manholes, or catch basins when surfacing or resurfacing a roadway. The extension member may be formed having a sloping upper planar support surface to thereby adjust the angle of the catch basin support frame or the manhole cover support frame. An outer surface of the extension member includes indicia that allows the user to align the slope of the upper planar support surface parallel with the roadway surface. When several sloped extension members are stacked, the indicia may be used to create a complex angle of slope relative to the underlying base members vertical axis. The extension member includes a pocket adaptable for receiving and retaining mortar between two stacked extensions. Planar surfaces may extend from both the upper and lower edge of the extension member, thereby providing support and added stacking surface for the stacked extension members. The extension member also includes a tapered shoulder that interlocks with either the manhole cone, the catch basin cone, or with other stackable angled plastic members.

Abstract: A cellular telecommunications system has a plurality of nodes, each for performing at least one of a number of cellular telecommunications system functions, including base station, speech coder, control processing, signal processing, local handoff, location register, and network interface functions. The nodes are interconnected by a network preferably comprising an optical fiber cable. In one aspect of the invention, the protocol that is used on the network is a high speed synchronous protocol, such as the DTM protocol. A first node in the system may be an antenna; an RF component coupled to the antenna; an analog-to-digital converter having an analog port, and a digital port being coupled to the RF component; and an optical fiber modem for connecting the digital port of the analog-to-digital converter to the network means. A second node in the system may be for performing base station controller functions, wherein the first and second nodes, together, operate as a distributed base station. In another aspect of the invention, some of the nodes may be transceivers, while other nodes include antennas coupled to frequency band filters. The network operates to permit any of the transceivers to be coupled to any one or more of the antennas, thereby permitting a handoff of a call from oneantenna to another while maintaining use of the same transceiver, or permitting a handoff of a call from one transceiver to another while maintaining use of the same antenna.

Title: Method of making injection molded orthotics
Inventor: MARSHALL SCOTT
IPC: B29C33/38
Filed: 1997-08-13
Granted: 2006-11-07
Abstract: A method of making functional orthotics from a multiplicity of uniquely designed injection molds which have been constructed by studying large numbers of replicas produced from uncorrected replicas that replicate the contour of the feet of a multiplicity of patients. In one form of the method of the invention, following a careful dimensional stu dy of the corrected replicas, they are grouped into families, the members of which exhibit lower surface contours that are substantially identical. An injection mold is then made for each of the identified families, in a manner such that the mold will produce an orthotic having an upper surface that corresponds to the lower surface of the corrected orthotic that makes up the group. Companion data is then developed which correlates the corrected replicas of each identified family with the uncorrected replicas from which they were made. A study of t he uncorrected replicas then provides data as to the contour of the patient's feet which they replicate. This data can then be compared with new patient data provided by the prescribing doctor and the mold can be selected which will produce an injection molded orthotic which i s appropriate for the particular patient.

Abstract: A method and system for detecting coincidences in a data set of objects, where each object has a number of attributes. Iteratively, equally-sized subsets of the data set are sampled, and coincidences (co-occurrences of a plurality of attribute values in one or more objects in the subset) are recopied. For each coincidence of interest, the expected coincidence count is determined and compared with the observed coincidence count; this comparison is used to determine a measure of correlation for the plurality of attributes for the coincidence. The resulting set of k-tuples of correlated attributes is reported, a k-tuple of correlated attributes being a plurality of attributes for which the measure of correlation is above a predetermined threshold. The method and system (implemented on an array of processing nodes) is suitable for protein structure analysis, e.g. in HIV research.
