An arrangement for handling communication messages in a building control system includes a communication circuit and a control device. The communication circuit is operable to generate first message and provide the first message on a communication network addressed to a remote building control system device. The communication circuit is also operable to receive a responsive message from the remote building control system device via the communication network, the responsive message generated by the remote building control system device responsive to the first message. The communication circuit is further operable to perform a first operation if the responsive message is received within a first time-out period, the communication circuit operable to perform a second operation if the responsive message is received after a first time-out period has expired. The control device is operably coupled to the communication circuit and is operable to use information from first message in a first application. The control device has a second application operable to generate a plurality of different time-out period values corresponding to a plurality of building control system devices, the plurality of different time-out period values including a value identifying the first time-out period the second application of the control device is further operable to provide information identifying the plurality of different time-out period values and their corresponding building control system devices to the communication circuit.

摘要:
A method of providing user interaction with a computer representation of a simulated object, where the user can control the object in three dimensions. The method can provide for two distinct states: a “holding” state, and a “released” state. The holding state roughly corresponds to the user holding the simulated object (although other metaphors such as holding a spring attached to the object, or controlling the object at a distance can also be suitable). The released state roughly corresponds to the user not holding the object. A simple example of the two states can include the holding, then throwing of a ball. While in the holding state, the method provides force feedback to the user representation of forces that the user might experience if the user were holding an actual object. The forces are not applied when in the released state.

In one set of embodiments, trimming of a reference, which may be a bandgap reference and which is configured on an integrated circuit, may be controlled by an algorithm executed by logic circuitry also configured on the integrated circuit. The bandgap reference may be configured to generate a reference voltage provided to an analog to digital converter (ADC) comprised in a temperature sensor that may also be configured on the integrated circuit. The logic circuitry may be configured to execute one or more of a variety of test algorithms, for example a Successive Approximation Method or remainder processing, that are operable to adjust values of reference trim bits used in trimming the bandgap reference. A tester system configured to perform testing of the integrated circuit may initiate execution of the test algorithm, thereby initiating the trimming process, and may wait for the test algorithm to complete within a previously defined amount of time, or may poll the logic circuitry to determine when the trimming process is complete.

An apparatus for opening a folding knife is provided. The apparatus may include a plate having an arcuate slot and a substantially linear slot. A cam slide may be provided comprised of an extension which extends into the substantially linear slot, and an opening into which a post connected to a blade device can be inserted. The extension of the cam slide typically can be moved in a substantially linear manner in the substantially linear slot. The substantially linear movement of the extension in the substantially linear slot causes a sharp edge of the blade device to come out of or go into a housing.

A system for rapid replacement of abrasive in machinery which uses the abrasive to finish the surfaces of workpieces that pass through the machinery on a belt, such as so-called widebelt sanders. One preferred embodiment of the system employs an abrasive material that is frictionally held on each edge to mounts. The position of the mounts may be varied to increase or decrease the tension of abrasive material against the working surface of the platen, that the assembly may be removed from the apparatus. In another embodiment, the abrasive material is formed with integral, permanent mounts on the edges of the abrasive material, so that the entire combination may be supplied or replaced as a unit. A variety of configurations of mounts may be used.
摘要:
A temperature sensor circuit and system providing accurate readings using a temperature diode whose ideality factor may fall within a determined range. In one set of embodiments a change in diode junction voltage (ΔVBE) proportional to the temperature of the diode is captured and provided to an ADC, which may perform required signal conditioning functions on ΔVBE, and provide a numeric value output corresponding to the temperature of the diode. Errors in the measured temperature that might result from using diodes with ideality factors that differ from an expected ideality factor may be eliminated by programming the system to account for differing ideality factors. The gain of the temperature sensor may be matched to the ideality factor of the temperature diode by using an accurate, highly temperature stable reference voltage of the ADC to set the gain of the temperature measurement system. The reference voltage may have a trim capability to change the gain setting voltage by a digital address comprising a determined number of bits, with the programmable range for the reference voltage corresponding to a determined range of ideality factors.

Optical parametric oscillators (OPO) and systems are provided. The OPO has a non-linear optical material located between two optical elements where the product of the reflection coefficients of the optical elements are higher at the output wavelength than at either the pump or idler wavelength. The OPO output may be amplified using an additional optical parametric amplifier (OPA) stage.
