Abstract: A system, device, and method for providing water, liquids, or beverages to a person while sitting in a seat are disclosed. The system and device can attach to a seat and support a liquid container. An attachment or object is used to support a hose in in a readily accessible location for a person to reach and grab the hose from the attachment or object used to support the hose. The system and device allow the person to access the water, liquids, or beverages with his or her hand while in the seat by pulling the hose from the attachment or object to hold the hose, then drink from the hose or mouth piece, and then return the hose to a position not directly on the body of the person after drinking that is supported by the attachment or object to hold the hose.

Abstract: A height adjustable bed framework 12 includes a base frame 24, an elevatable frame 30, a lift chain 50 and a power module 52. The lift chain is connected to the base frame or the elevatable frame and the power module is connected to the other frame. The power module includes an energy converter such as an electric motor 90, a planetary gear train 110 driven by the energy converter and a chain driver, such as a sprocket 160, engaged with the lift chain and driven by the planetary gear train.

Abstract: A combined siderail/over-bed table unit 42 for a bed 20 has a table position in which at least part 62 of the unit overlies a mattress region 48 of the bed thereby serving as an over-bed table and also has a siderail position allowing the unit to serve as a siderail.

Abstract: A siderail assembly comprises a first siderail body and a second siderail body. The second siderail body is movably coupled to the first siderail body and configured to rotate between a first position and a second position with respect to the first siderail body about a rotational axis passing through the first siderail body. The second siderail body is positioned above the first siderail body in the first position and below the first siderail body in the second position.

Abstract: A central vacuum connectable to an interior portion of an inhabitable structure. The central vacuum system includes a housing having a first housing member and a second housing member secured to the first housing member. Together the first housing member and the second housing member at least partially define a collection chamber. A vacuum motor is supported by the housing and is operable to move debris from the interior portion into the collection chamber. An adapter extends into the collection chamber for supporting a bag. At least one of the bag and the adapter are accessible through an opening defined in one of the first housing member and the second housing member.

Abstract: New biochemical protocols for high throughput processing of mRNA samples into cDNA libraries with adaptor sequences compatible with automated sequencing systems are provided. The provided methods produces cDNA libraries which do not have 3? bias associated with current cDNA library production methods. New methods for the production of DNA libraries from DNA are also provided.

Abstract: The present invention provides for a method of preparing a target nucleic acid fragments to produce a smaller nucleic acid which comprises the two ends of the target nucleic acid. Specifically, the invention provides cloning and DNA manipulation strategies to isolate the two ends of a large target nucleic acid into a single small DNA construct for rapid cloning, sequencing, or amplification.

Abstract: A central vacuum system connectable to an interior portion of an inhabitable structure includes a housing having an upper end, a lower end, and a side wall defining a collection chamber, the side wall defining an opening communicating between atmosphere and the collection chamber, and a vacuum motor supported in the housing and being operable to move debris from the interior portion into the collection chamber.

Abstract: An ultrasonic diagnostic scanner for obtaining ocular measurements is described. The ultrasonic diagnostic scanner generally comprises transmitter means for generating an ultrasonic signal, receiver means for receiving echo signals and for producing a peak signal at substantially the maximum amplitude of the echo signals when the echo signals exceed a predeterminable threshold level, programmable means for producing count signals indicative of the times between the transmission of the ultrasonic signal and the occurrence of a selected number of peak signals, and between the occurrence of predetermined peak signals, microcomputer means for controlling the transmitter and programmable means, and output means for generating a perceptible output indicative of the ocular parameter being measured. The ultrasonic diagnostic scanner also includes sensitivity adjustment means for maintaining a predetermined amplitude level of at least one of the echo signals under the control of the microcomputer means.
