A portable peritoneal dialysis system for a patient includes an inlet port for providing inflow to the patient's peritoneal cavity, an outlet port for providing outflow from the patient's peritoneal cavity, and a volume of dialysate for flow into and out of the patient's peritoneal cavity, thereby removing from the dialysate uremic waste metabolites that have diffused into the dialysate. The portable peritoneal dialysis system also includes a closed liquid flow loop, including a pump, for flowing the dialysate into and out of the patient's peritoneal cavity, and an organic- and phosphate-removing stage, including at least one replaceable cartridge in the closed liquid flow loop, the cartridge containing material for removing organic compounds and phosphate from dialysate removed from the patient's peritoneal cavity. The portable peritoneal dialysis system further includes a urea- and ammonia-removing stage, including at least one replaceable cartridge in the closed liquid flow loop, the cartridge containing material for removing urea and ammonia from dialysate removed from the patient's peritoneal cavity, the material being packed around semi-permeable hollow fibers with interior fiber walls that reject cations, thereby retaining cations in the dialysate.

A winder is provided near a quarter window of a rear door. A shade member is drawably mounted about the winder. A connecting piece is connected to a drawing arm and mounted to the rear portion of the shade member. A shoe is mounted to a bottom end of the drawing arm. The shoe engages with a regulatory groove extending in a drawing direction of the shade member. A driving cable is connected to the shoe. The shade member can be drawn out across the window by the drawing arm via the sending out of the driving cable by an operating mechanism. Since the regulatory groove extends substantially in a circle, when the shoe moves through engagement with the regulatory groove, the connecting piece connected to the drawing arm pivots relative to the shoe.

The present invention provides the art with a scroll machine which has a plurality of built-in volume ratios along with their respective design pressure ratios. The incorporation of more than one built-in volume ratio allows a single compressor to be optimized for more than one operating condition. The operating envelope for the compressor will determine which of the various built-in volume ratios is going to be selected. Each volume ratio includes a discharge passage extending between one of the pockets of the scroll machine and the discharge chamber. All but the highest volume ration utilize a valve controlling the flow through the discharge passage.

Magnification glasses and methods of use, the glasses including a first camera array for capturing a magnified image in the field of view of the glasses, the first camera array including a first camera and a second camera, where the first camera and the second camera provide different levels of magnification, where the first camera and the second camera have the same working distance of between 150 mm to 400 mm, and where the first camera and the second camera are fixed focus cameras.

The invention provides a satellite-borne S-band measurement and control antenna, which comprises a choking coil, a protection cover, four-arm spiral band and a phase shifter, and is characterized in that the choking coil is integrally machined, and the overall dimensions and the number of turns of the choking coil can be adaptively changed according to different electrical indicator requirements; the protection cover is molded by a composite material and is effectively adhered to the choking coil so as to form a compact structure; the four-arm spiral band is of a pure metal structure and divided into an inner cylinder and an outer cylinder; phase shifter does not contain a component inside and realizes phase shifting through a metal strip line; and the four-arm spiral band and the phase shifter are designed into a modular assembly and assembled according to different antenna turning direction requirements. Therefore, the antenna provided by the invention has the characteristics of miniaturization, hemispherical beam, wide-angle circular polarization, broadband and the like, the phase shifter of the antenna does not contain components, and the phase shifter and the four-arm spiral band realize radio frequency connection through structural plugging, so that the satellite-borne S-band measurement and control antenna realizes compact structure, miniaturization, light weight and high reliability.

The invention provides an ultra-wide-angle optical imaging system and optical equipment. The ultra-wide-angle optical imaging system sequentially comprises a first lens group with negative focal power, a second lens group with positive focal power, an aperture diaphragm, a third lens group with positive focal power, a twelfth lens with negative focal power and a fourth lens group with positive focal power from an object side to an image side, in the focusing process, the twelfth lens moves towards the image side along the optical axis, and the positions of the first lens group, the second lensgroup, the third lens group and the fourth lens group relative to the image plane remain unchanged. The first lens group satisfies the following conditional expressions: -2.8 < = F1 / F < = 1.3, (1); the second lens group satisfies the following conditional expressions: 1.8 < = F2 / F < = 2.6, (2). The invention further provides optical equipment provided with the ultra-wide-angle optical imaging system. The focusing assembly of the imaging system is composed of only one lens, so that the weight of the focusing assembly and the total weight of the optical imaging system are reduced, and meanwhile, quick focusing of the optical imaging system and imaging equipment is facilitated.

Provided is a thermistor fixing structure capable of facilitating insertion of a thermistor into a temperature sensitive cylinder, and preventing the thermistor from easily dropping off the temperature sensitive cylinder. In a thermistor fixing structure (4000), a fixture (400) for pressing a thermistor (80) against an inner surface of a temperature sensitive cylinder (90) includes an inner bending section (20) formed at one end portion (12) of a longitudinal section (10) so as to function as a stopper for the thermistor (80) inserted into the temperature sensitive cylinder (90) from a cylinder insertion end (95), an outer bending section (50) formed at the one end portion (12) of the longitudinal section (10) so as to be opposed to a cylinder stop end (94), and an inner folding section (30) and an outer folding section (60) formed at another end portion (13) of the longitudinal section (10) so as to sandwich a cylinder top surface of the temperature sensitive cylinder (90). A side surface of the thermistor (80) is pressed at two points corresponding to an apex of a projecting portion (32) formed on the inner folding section (30) and a distal end (41) of a pressing section (40) formed continuously with the inner folding section (30), and a contact angle (α) formed between the pressing section (40) and the side surface of the thermistor (80) on the cylinder insertion end (95) side is an acute angle.

Techniques are disclosed for creating optical systems and devices that provide through-sight information while enabling the optical systems and devices to maintain a small, lightweight form factor. According to certain embodiments of the invention, an optical assembly can include a liquid-crystal display (LCD) disposed between the two prism elements of a Schmidt-Pechan prism at a focal plane of the optical assembly. This allows the LCD to be used to display information by blocking light passing through the optical assembly. Additionally, a light-emitting display, such as a backlit LCD, light-emitting diode (LED) display, or organic LED (OLED) display, can be coupled at a surface of one of the two prism elements of the Schmidt-Pechan prism to provide additional information in low-light environments.
