Abstract: A pressure-actuated switch having a pressure port, a diaphragm, a range spring, an actuator plate, a differential plate, and an electrical switch. A certain pressure level moves the diaphragm against the range spring at the pressure port and thus deflects the actuator plate. The actuator plate is coupled to the electrical switch via a snap spring, wherein the electrical switch can be switched on or off via the deflection of the actuator plate and the snap spring. The differential plate controlled by a differential spring is connected to the actuator plate and supports the actuator plate in a first portion of movement, wherein the differential plate is decoupled from the actuator plate in a second portion of movement of the actuator plate.

Abstract: A computing device, having a user input interface including an input button, processes a sentence array including component words of a target sentence string to determine at least one target word to be read by the user. The computing device detects press and hold by the user of the input button, and in direct response, receives and processes user speech input to recognize at least one spoken word, and upon recognizing the at least one spoken word, determines whether the user has correctly read the at least one target word. The computing device also detects release by the user of the input button, and in direct response, identifies a context position relative to the target sentence string, and processes at least one predefined action based on the identified context position.

Abstract: A method of measuring performance of a transaction over a network. The transaction includes requesting information from an information source connected to the network and interacting with the information source. The method includes connecting a data acquisition agent to the network, sending a request for information from the data acquisition agent to the information source, and loading data responsive to the request for information onto the data acquisition agent. The transaction is executed and performance measurements for the transactions are collected and sent to a storage device. A system for measuring performance of a transaction over a network is also disclosed.

Abstract: A system for measuring performance of streaming media sent from a server over a network. The system includes a data acquisition agent connected to the network and operable to send a request for streaming media to the server. The agent is configured to receive streaming media, collect performance measurements, and send the performance measurements to a storage device.
