The invention is a signal processing system and method having increased bandwidth. An embodiment of the invention is a method of processing an analog input signal. The analog input signal is split into a first set of signals. The first set of signals are filtered. The first set of signals are digitized to form a second set of signals. The second set of signals are filtered to form a third set of signals. The third set of signals are combined to form a combined signal by adding the signals in the third set signals together to form a digital version of the analog input signal.

An consumer contact toll optimizer providing for the automatic disconnection and reconnection of communication links between communications devices and/or services is provided. The system allows communication links to be terminated before a specified period of time has elapsed, thereby allowing consumers of communications services charging on a time of use basis to minimize the charges incurred while using such services. In particular, the present invention allows consumers to minimize fees in connection with communications networks that charge at a first, lower rate for an initial period of time, and a second, higher rate for subsequent periods of time. The present invention is particularly well-suited for use in connection with wireless telephones having service plans that do not charge for the first incoming minute of a telephone call, and in connection with long distance service plans that charge a lower rate for an initial period of time and a higher rate for a subsequent period of time.

A method for wafer backside alignment overlay accuracy includes forming a buried layer on a front-side of a wafer; forming a conductive layer on the buried layer and patterning a first test structure and a second test structure therein; forming an etch stop layer on the conductive layer; etching through the wafer from the backside to perform an alignment process with the first test structure; and determining an overlay accuracy of the alignment process with the second test structure. The first test structure includes an optical vernier and the second test structure includes an electrical testing structure.
摘要:
The present invention provides a system for monitoring a physiological parameter of players engaged in a sporting activity. The system includes a plurality of reporting units, a controller, and a signaling device. The reporting unit has an arrangement of sensing devices that measure the physiological parameter of an individual player and generate parameter data. The controller receives the parameter data transmitted from each reporting unit and then processes the parameter data to calculate a parameter result. When the parameter result exceeds a predetermined value, the controller communicates with a signaling device that provides an alert to sideline personnel to monitor the player(s) in question. The system also includes a remote storage device for holding historical data collected by the system which permits subsequent analysis. The system can monitor a number of player physiological parameters, including the acceleration of a player's body part that experiences an impact and the temperature of each player.

The present invention provides an apparatus and method for determining the magnitude of linear and rotational acceleration of an impact to a body part. The apparatus can be used with protective sports equipment, such as a sports helmet, wherein the apparatus includes a battery, a number of accelerometers positioned proximate to the outer surface of the head, and an electronic device with a processor and a transmitter to transmit data received from the accelerometers. To maximize the battery life and minimize power consumption by the electronic device, the apparatus includes a power management system with a sensor assembly. The sensor assembly sends a first signal to the electronic device to initiate operation when the sensor assembly detects the presence of an object within the helmet, and a second signal to the electronic device to cease operation when the sensor assembly detects the absence of the object. The sensor assembly may be a proximity sensor, more specifically an inductive, capacitive, or ultrasonic sensor.

A system for distributed networking of geolocation equipment includes a plurality of sites having geolocation equipment, each instance of geolocation equipment being coupled to a network, and a service provider coupled to the network. In exchange for ownership and use of geolocation equipment provided by the service provider, an operator of the geolocation equipment allows the service provider to access to the geolocation equipment over the network for use in locating unknown transmitters.
摘要:
The invention relates to a system for monitoring a physiological parameter of players engaged in a sports activity. The invention further relates to a method for evaluating and treating players when the parameter exceeds a predetermined level. The system measures, calculates and records the parameter and then alerts trained personnel to apply the method to evaluate and treat players. When the system is configured for use with football, hockey or lacrosse, the system generally includes reporting units, a sideline controller, a database, and a signaling device, such as a wireless personal digital assistant. The physiological parameter data measured and collected by the reporting units are processed by the sideline controller for meaningful analysis or use. When the physiological parameter(s) exceeds a predetermined threshold level the sideline controller generates an alert that is received by the signaling device, which is typically worn by sideline personnel, such as coaching staff or trainers. After an alert occurs, the method for evaluating and treating a player is initiated. The signaling device includes software that prompts the sideline personnel to perform the method through a series of interactive steps and tests. The signaling device prompts the personnel to conduct the appropriate sideline examination, records the responses, compares the results to established baselines and prompts further testing, a return to play decision, or a no-play decision.
摘要:
A generic and dynamically-modifiable database schema has a tree structure that includes leaf nodes each defining a value of an attribute, branch container nodes each representing a different attribute and identifying those leaf nodes that define values of the container node's attribute, root nodes each representing a database record and identifying those leaf nodes in different container nodes that define values of an attribute of the root node's record, a root container node representing a database and identifying the root nodes that represent its records, attribute nodes each representing a different attribute and identifying the ii branch container node that represents that attribute, and a map container node identifying attribute nodes. Each leaf, root, and attribute node is a data structure that defines a name of an attribute, a value of the named attribute, and an identifier—an index or a dictionary—of zero or more nodes that define values of attributes of the named attribute's value. Attribute nodes lack the value. Each container node is a table, a dictionary, or an array. The schema further includes operations to insert, update, and delete records, and to add and delete attributes.
