  • Publication number: 20220347385
    Abstract: A medical device such as an infusion system detects that an accessory has been coupled to the device. The medical device initially operates in a first mode of operation. The medical device, in response to the detecting, associates the accessory with a different mode of operation for the medical device that requires changes to at least one of the operating parameters for the infusion system or elements within a graphical user interface. The medical device then automatically changes the mode of operation from the first mode of operation to the associated different mode of operation to reflect the coupling of the accessory to the infusion system. Related apparatus, systems, techniques and articles are also described.

  • Publication number: 20070116471
    Abstract: A node for use in a wireless communication network that facilitates alignment of the node with other nodes in the network and a method for aligning the node. The node includes mounting fixtures that enables the mounting of GPS receivers and a tiltmeter to obtain position and bearing information for the node. The node contains alignment features that enable the positioning of an optical transmitter/receiver pair in the node using the data obtained from the GPS receivers and tiltmeter.

  • Publication number: 20060291866
    Abstract: Systems and methods for use with an optical communication beam are disclosed. The system allows the beam of light to operate at an adequate power level that provides a robust optical link while minimizing any safety risk to humans. The system calibrates and controls the gain for an avalanche photodiode detector (APD). A detector circuit is used to calibrate the APD. Once calibrated, the detector circuit further provides an electrical bias to the APD to process or condition the electrical signal to produce a detector output. The systems and methods disclosed herein attenuate the power level of an incoming communication beam to prevent oversaturation of an APD. The system further provides an alignment signal, which is effective over a wide dynamic range of incoming power levels.

  • Publication number: 20060232186
    Abstract: The disclosed method for forming a field emission display includes forming a cathode and an anode, forming a plurality of photoresist posts over the cathode, and coating the posts with a layer of coating material. The layer of coating material forms sidewalls around the posts. The photoresist posts may then be removed from within the sidewalls. The anode may then be fitted onto the sidewalls so that the sidewalls function as spacers in the field emission display.

  • Publication number: 20060067476
    Abstract: A laser produced plasma device comprises a shutter assembly for mitigating the contaminating effects of debris generated by the plasma. In one embodiment, the shutter assembly includes a rotatable shutter having at least one aperture that provides a line-of-sight between a radiation source and an exit of the device during a first period of rotation of the shutter, and obstructs the line-of-sight between the radiation source and the exit during a second period of rotation. The shutter assembly in this embodiment also includes a motor configured to rotate the shutter to permit passage of the X-rays through the at least one aperture during the first period of rotation, and to thereafter rotate the shutter to obstruct passage of the debris through the at least one aperture during the second period of rotation.
