Abstract: The disclosure is directed to an article includes a first layer and a second layer. The first layer includes a silicone base polymer and a hydride-containing siloxane, wherein the hydride-containing siloxane is present at about 0.1% by weight to about 5.0% by weight of the silicone base polymer and the second layer includes a fluoropolymer.

Abstract: The disclosure is directed to a sealing assembly. The sealing assembly includes a cap having a top surface and a bottom surface, an adhesive layer adjacent the bottom surface of the cap, and a septum adjacent to the adhesive layer. The adhesive layer includes a self-bonding silicone composition and the septum includes at least one fluoropolymer layer. The disclosure is further directed to methods for making the aforementioned sealing assembly.

Abstract: A system includes a cap having an opening, and a septum configured to engage with the cap. The septum includes a first portion having a first width, and a second portion having a second width smaller than the first width. The second portion is sized and shaped to be received by the opening of the cap.

Abstract: Embodiments of this invention provide for a portable computer that determines whether an accessory device is actively connected to it. In one embodiment, the portable computer may include a signal line accessible through an output of the portable computing device. The signal line may be connected to a communication device such as a communication cradle. The portable computer may detect a signal on the signal line to determine whether the communication device is actively connected to the portable computer. If the communication device is actively connected, the portable computer suspends implementation of a time-out feature that would otherwise reduce power consumption of the portable computer.

Abstract: Methods and apparatus are provided for reserving power in a handheld computer by inducing a sleep mode when the energy supply of the handheld computer reaches a predetermined low level. A software is provided which operates a sleep mode when a device of the handheld computer detects a predetermined low battery voltage. A processor operates the software to place the handheld computer in a low energy-consuming shutdown state in which an interrupt controller operates to mask those interrupt signals thus providing an user with the impression that the device has entered an unresponsive sleep mode. In maintaining the sleep mode, the processor operates such that all input signals that request the handheld computer to power up remain active but so long as the battery voltage remains below a predetermined voltage the interrupt signals to power up selected applications and devices are masked.

Abstract: A projection system is provided having an aerosol generator for producing aerosol in a defined space. At least two light beam generators are arranged to direct light beams from at least two different positions onto the aerosol. Projection controls are adapted to convert three-dimensional image data into projection signals which are supplied to the light beam generators to project the three-dimensional image to become visible in the aerosol space.

Abstract: Embodiments of the invention provide for operating a handheld computer with multiple time-out periods in a manner that is more efficient and effective for conserving power than previous systems. In an embodiment, the handheld computer implements one or more additional time-out periods by identifying an occurrence of an event that requires the handheld computer to be in the high power state to perform a specific function. An event may include a function such as sounding an alarm, although other events are also encompassed by embodiments of this invention. When an event is identified, the power state of the handheld computer prior to identifying the event is recalled. The handheld computer then implements a time-out period based on its previous power state. In one embodiment, if the handheld computer was in a low-power state prior to the event occurring, the time-out period is shortened.

Abstract: Methods and apparatus are described for providing a time-based warning indicating that the energy capacity of a primary energy source of a battery-powered computer has discharged to a low level, and using residual energy of the primary energy source to perform at least one pre-cutoff function. The time-based warning ensures that the warning is provided in a timely manner by overcoming problems caused by analog to digital converter voltage measurement accuracy limitations and flat battery operating voltage versus discharge curves. The primary energy source can be a rechargeable battery, which can also be the sole energy source for the computer. The battery provides power to operate the computer until the battery voltage discharges to the cutoff voltage. The methods and apparatus provide advantages because they reserve the residual energy in the battery to perform at least one pre-cutoff function within a first duration before the battery discharges to the cutoff voltage.

Abstract: The invention is a contaminant removal system for purifying air. Incoming air is cooled to a cryogenic temperature. A vortex tube further cools the cooled air so as to solidify contaminants therein. A filter system then filters out the solidified contaminants from the air.Use of a vortex tube minimizes the amount of moving parts. This reduces maintenance and concommitant costs involved with operation. The present system has a long life. The vortex tube is relatively inexpensive.
