摘要:
An apparatus may include a housing having an inner surface and an outer surface, a mirror coupled to the inner surface of the housing, and a receiver unit coupled to the housing. The mirror is to receive direct radiation and to focus the radiation toward a localized area, and the receiver unit is to receive the radiation directly from the mirror and to convert the received radiation to electrical current.Some aspects include a first mirror to receive a portion of direct radiation and to reflect the received portion of direct radiation toward a first localized area, a second mirror to receive a second portion of direct radiation and to reflect the received second portion of direct radiation toward a second localized area, and a receiver unit to receive the reflected portion of direct radiation directly from the first mirror and to convert the received radiation to electrical current. The receiver unit is disposed under the second mirror and is not coupled to a back side of the second mirror.

A test head for an integrated circuit tester includes a main chassis defining a chamber that is open at the top. Tester modules are installed in the chamber, each tester module being removable as a unit from the chamber and including a tester module chassis, multiple pin electronics cards, and a tester module interface structure exposed at the top of the chamber. A test head interface structure is engageable with the tester module interface structures of the tester modules for connecting the tester module interface structures to a device interface unit.

The present invention is directed to a device and method for securing optical elements in a solar energy system. Molded securing devices are fixed directly to the front panel of a solar energy system to provide for secure, aligned placement of optical components. In some embodiments, the peripheral edge of a front panel may be encapsulated by the molded device to provide alignment of peripheral optical elements and a secure water resistant seal between the front panel and a backpan. In other embodiments, molded securing devices may be positioned away from the peripheral edge to assist in alignment of central optical elements.

The systems and methods provide a dynamic process for obtaining and managing informed consent documentation. In general, the dynamic informed consent process (DICP) makes use of an intermediary organization, e.g., a trusted intermediary, which: (a) provides ICFs which have been dynamically generated for a specified trial or medical procedure and based on particular state or federal requirements, if any; and (b) archives copies of signed ICFs. In certain preferred embodiments, there may also be a procedure to provide training materials, such as audio or video presentations, to be viewed by prospective participants. In certain preferred embodiments, the process also includes contacting subjects who have signed ICFs in the event that there is a change of circumstance which the subject may deem material to whether s/he would continue to consent, or whether the participant needs to provide a different type of consent to participate in particular event or trial.
摘要:
An airway device (14), that is used to maintain a clear airway in a patient, e.g. for artificial ventilation during surgery, comprises an inflatable cuff (26), which is inflated when in position in a patient's airway (24). The inflated cuff (26) provides a seal to maintain the device (14) in position in a patient's airway (24), and to prevent leakage of infected oropharangeal secretions into the patient's lungs. A method and apparatus (10) for monitoring and controlling the pressure in the inflatable cuff (26) is described, which, in one embodiment, controls the pressure about a setpoint pressure, whilst preventing loss of sealing pressure during a patient's respiratory cycle. In other embodiments, the method and apparatus monitors for: leaks in the pressure system of the device (14) that includes the cuff (26); blockage in the pressure system, and/or malpositioning of the airway device (14) during use.
摘要:
A solar thermal energy collector manifold is provided. The manifold is connected to solar collector tubes for collecting solar energy. A fluid is used to transfer the heat collected from the collector tubes. The manifold includes an inlet path for receiving the fluid, a fluid flow path for transferring the fluid to the solar collector tubes, and an outlet path for outputting the heated fluid. To facilitate the flow paths, the manifold includes a plate with depressions.

The present invention is a solar tracking system which utilizes three supports arranged in a generally tripod configuration. In one embodiment, two of the supports are linear actuators, and the third support is a stationary universally pivoting joint such as a ball and socket joint. The tracking system may include cross-supports for increased stability, a linear rail for additional range of motion, and a mounting base to facilitate installation. This solar tracking system offers a stable, cost-effective design which is also capable of moving the solar module into an optional stowed position.
