摘要:
Methods and systems for configuring nodes in a redundant network configuration include identifying a master node from a plurality of nodes in the network by sending a configuration packet to each node. The configuration packet includes an identification number representing the node in the network from which the configuration packet originates, where each node in the network has a unique identification number. At each node in the network, the identification number in the configuration packet is compared to an identification number for that node. In one embodiment, the node whose identification number is greater than the identification number in the configuration packet is designated the master node. A virtual break is created in the network at the location of the master node to prevent a packet from returning to the node from which it originates.

In digital display circuitry, configured to display an image encoded in an analog display signal, the digital display circuitry includes analog-to-digital converter (ADC) circuitry to recover pixel data elements of the image. During vertical blanking intervals of the analog display signal, the ADC circuitry is calibrated. Outside the vertical blanking intervals, the ADC circuitry is used to convert information in the analog display signal into digital representations of the pixel data elements. For example, the calibrating may include determining more acceptable values for certain ones of the operational parameters of the ADC circuitry.

A dispenser (10) uses first and second flow controls (70, 73). The flow controls maintain first and second flow ranges independent of diluent pressure within a pressure range, wherein the use solution's concentration is maintained over the pressure range. A third flow control (75) may also be utilized in a third diluent passageway for maintaining a third flow range independent of the diluent pressure within the pressure range. A bypass valve assembly (41) is operatively connected to the third incoming diluent passageway. The bypass valve has a temperature control valve. The temperature control valve having a bypass passageway, wherein additional diluent is added to the use solution, thereby controlling the use solution's concentration.

An optical element mounting includes a frame, and a shuttle that is translatable relative to the frame. The shuttle includes inner and outer portions that are mechanically coupled together by a plurality of flexures that effectively bending and twisting of the shuttle from being transmitted to an optical element, such as an optical window, that is mounted on the inner portion of the shuttle. The flexures may be thin linking strips of material between the outer and inner portions. The flexures may have a thickness that is greater in an expected load direction, than in a direction perpendicular to the load direction. The optical mounting may include a locking mechanism, for example including a shape memory alloy wire, to lock the shuttle in a predetermined location relative to the frame.

A method of managing correctional and/or rehabilitation programs for substance abuse for a number of entities having jurisdictional responsibility for persons, the method comprising: receiving correctional and/or rehabilitation data from a plurality of entities having jurisdictional responsibility for persons, said correctional and/or rehabilitation data including information on substance abuse by persons for which said entities have jurisdictional responsibility; processing the received correctional and/or rehabilitation data to aggregate the data and reference the data by each entity to allow for comparative analysis of the correctional and/or rehabilitation programs; storing the processed correctional and/or rehabilitation data in a central database; and managing the correctional and/or rehabilitation programs dependant upon the processed data.
摘要:
A low product indicator (20) includes a cap (21) having an aperture (22) and a rod (23) extending through the aperture (22) for contacting a product (17). A biasing member (25) is operatively connected to the rod (23) thereby biasing the rod (23) against the product (17) allowing the rod (23) to move through the cap (21) as the product (17) is dispensed. Visual indication of a level of the product (17) is evident as the rod (23) moves through the cap (21).
摘要:
A portable dispenser including a concentrate reservoir configured within the dispenser; a use-solution reservoir configured within the dispenser and positioned adjacent the concentrate reservoir; means connecting the concentrate reservoir and the use-solution reservoir, the connecting means providing for fluid flow between the concentrate reservoir and the use-solution reservoir; an inlet for introducing diluent into the dispenser; and means for generating a use-solution by drawing concentrate from the concentrate reservoir, whereby when a diluent is introduced into the dispenser inlet, the use-solution generating means is activated drawing concentrate from the concentrate reservoir and mixing the concentrate with the diluent to form a use-solution.
