A via resistor structure and method are provided for implementing a resistor and for trimming a resistance value of the resistor. A resistive material selectively is deposited adjacent to a pad connecting to a via where a resistor is to be defined. A trimmed path is formed in the resistive material for selectively changing the resistance value of the resistor.

A device (30) for making electrically conductive contact with at least one tension member in an elevator belt (22) also provides a restraining feature to support loads on the belt. A connector portion (32) is secured to the belt. In one example, the connector portion (32) includes clamping members (40, 42) that are received on opposite sides of the belt. One of the clamping members supports a plurality of electrically conductive connector members (52) that establish electrical contact with selected tension members (24) within the belt (22). A plurality of load transferring members (66) are supported by the other clamping member in one example. A restraining portion (34) is adapted to be secured in a fixed position relative to a selected structure (36) within the elevator system. An opening (38) through the restraining portion (34) allows the belt (22) to pass but prevents the connector portion (32) from moving beyond the restraining portion (34) as the outside dimension of the connector portion (32) is larger than the size of the opening (38). In one example, high temperature resistant materials such as steel or ceramics are used for the restraining portion (34) and the clamping members (40, 42).

An intelligent network for providing access to an information network (80) has a number of central office switches (64, 82). Each central office switch (64, 82) is capable of receiving a call to a centrex telephone number and transmitting a query. A service control point (70) is coupled to the central office switches (64, 82) by a SS7 signal link (66). The service control point receives the query and transmits a response to the central office switch (64, 82). A hub switch (75) is coupled to the central office switches (64, 82) and receives the call. The hub switch (75) contains a digital trunk service (76) that combines the call with a number of other calls to form a data stream. The data stream is then transmitted to an information network node (80).
摘要:
A high frequency connector utilizes flex strip signal/reference conductor pairs extending in channels formed in a dielectric connector body between terminations at connector ends. The flex strips are formed as signal and reference conductor traces separated by a flexible dielectric wherein the impedance can be influenced by the width of the signal and reference traces and the thickness and selected material of the dielectric separating the adjoining conductor traces. Design of the flex strip assemblies is used to vary the capacitance which enables the connector impedance to match the impedance of the circuits and/or cables connected to the connector and mitigate any discontinuities among the sequence of circuit paths. The close proximity of signal and reference traces within the pair and the separation of signal lines in the connector body reduces cross talk by minimizing mutual inductance between signal lines.

A safety braking disk (56) is secured to rope drive sheave (14). First (52) and second (54) safety brake assemblies each operate on opposing parallel sides of the disk. Brake pads (60) are resiliently placed into engagement upon initiation of the safety. The safety is initiated upon car overspeed, movement with open car doors, or excess velocity in the leveling zone.
摘要:
An apparatus and method for simulation and testing of electronic systems using a single model that has the composite behavioral information of multiple parts. The single model allows the designer to simulate using one model that captures the anticipated extremes (best case behavior to worst case behavior) across a collection of devices from different vendors.

In general, the invention is directed to data exploration and visualization techniques that allow a user to more easily apply multivariate statistical analysis to a dataset. In one embodiment, the invention provides a method comprising identifying a set of data clusters associated with two or more components of resolved data generated from a dataset by Multivariate Curve Resolution; and rendering a Principal Component Analysis scatter plot of the data clusters for principal components of the dataset using the data clusters identified from the MCR data.
