摘要:
A blood pressure measurement apparatus for use in association with a blood pressure measuring cuff includes a housing having an upper shell and a lower shell defining an interior chamber and a replaceable module disposed within the interior chamber. The replaceable module houses a pump for inflating the blood pressure measuring cuff and a vent valve for venting the blood pressure measuring cuff. A cuff pressure sensor is provided within the interior chamber, either within or externally of the replaceable module. A control circuit for controlling the pump and the vent valve is provided on a circuit board disposed externally of the replaceable module. A power pack may be provided within the replaceable module for supplying electric power to the pump, the valve, the control circuit and other components within the interior chamber.

The collector/concentrator includes a primary concave reflector (1) supported on a base body (3) obtained by injection moulding, which defines a central support (5) supporting a region around a central opening (6) of the primary reflector (1), a plurality of peripheral legs (7) supporting respective peripheral regions of the primary reflector (1) and first integral connection members (8) connecting said peripheral legs (7) with the central support (5). The peripheral legs (7) have bottom ends (7a) leaning on a substantially flat supporting surface and top ends (7b) located above the peripheral regions of the primary reflector (1) that are in contact with a substantially flat transparent panel (15) supporting a secondary convex reflector (2) that concentrates the solar radiation reflected by the primary reflector (1) towards a receiver unit (18) through the central opening (6).

The invention includes a fixed platform bearing a circular rail, supporting rolling elements to which is attached a mobile frame with a sloping structure which holds a number of solar panels, grouped in rows, the panels of each row being connected to corresponding support shafts, supported on the sloping structure, and a device for moving the frame and shafts in accordance with a predetermined configuration. The frame includes a base with attached thereto the rolling elements and the sloping structure is raised above the base, at a distance from the fixed platform and formed by two supporting beams that delimit an oblique plane and are separated from each other by a distance greater than the diameter of the rail.

The solar tracker comprises a base (1) and a solar panel (2) having first and second opposite ends (2a, 2b). The first end (2a) can be connected to the base (1) by a first shaft (E1) and the second end (2b) can be connected to the base (1) by a second shaft (E2), such that said solar panel (2) can pivot with respect to the base (1) alternately around the first shaft (E1) and around the second shaft (E2) under the drive of a lifting mechanism. An automatic connection/disconnection device connects the second end (2b) of the solar panel (2) to the base (1) while at the same time disconnecting the first end (2a) of the solar panel (2) from the base (1), and vice versa, every time the solar panel (2) reaches a position parallel to the base (1) for inverting the inclination of the solar panel (2) with respect to the base (1).

摘要:
The present invention relates to a single-axis solar tracker and solar power installation. The tracker comprising: a row H1 of coplanar and adjacent solar panels P secured to a horizontal common rotating shaft E1; a support structure wherein said common rotating shaft E1 is rotatably mounted, actuation means with a geared motor M in connection with a part P1 in the form of a circular sector secured to the common rotating shaft E1, and a support base B1 attached to the ground wherein said support structure and said geared motor M are secured. The solar power installation comprises the solar tracker proposed with its actuation mechanism in mechanical connection with a series of actuation mechanisms of other solar trackers included in the installation.
摘要:
A pressure measuring apparatus includes a gage that is at least partially imbedded within a flexible elastomeric member disposed within an interior cavity of a device housing. A shock resistant member into which the gage is inserted permits fluid interconnection between the interior of the gage having a contained movement mechanism that is responsive to fluid pressure changes and a fluid source, such as an inflatable blood pressure cuff and further provides shock and/or impact resistance for a contained movement mechanism. Additional impact/shock absorption is provided by exterior features of the apparatus, including a peripheral bumper having a plurality of raised spring-like protrusions, and rubberized and contoured features of the device housing.
