In a further embodiment, the breast fixation device consists of multiple inflatable fingers which drape around the breast tissue and then squeeze the breast tissue into an elongated position as they are inflated.

Abstract: In various embodiments, methods and devices are provided for generating a radiotherapy treatment plan for a subject to be implemented on a radiotherapy device. In certain embodiments the methods involve determining all feasible radiotherapy beam orientations free of collision for said radiotherapy device and said subject to provide a set of radiotherapy beam orientations; selecting from the set of all feasible radiotherapy beam orientations a subset of beams that meet treatment goals to be used in treatment of the subject to provide a selected beam set; calculating a navigation trajectory for the radiotherapy device to delivery said subset of beams to the subject where the trajectory is free of collision; and generating and writing instruction files to a tangible medium that can be executed by said radiotherapy device.

Abstract: A display device comprises a cover and a display module. The cover includes a bottom plate and at least one cover limit element.

Abstract: A magnetic connection structure, includes a ring-shape magnetic sleeve body, made of mixed magnetic iron powder and plastic by means of ejection-to-mode; and a plastic fastener, provided in an arc-shape opening on both sides of the ring-shape magnetic sleeve body, for fastening a faucet seat or an ejection head. In the magnetic connection structure, the magnetic sleeve body and the plastic fastener are formed by means of ejection-to-mode separately. The magnetic sleeve body is formed by ejection-to-mode using magnetic iron powder and plastic mixed at a certain ratio; while the magnetic fastener is formed by means of ejection-to-mode separately. Then, the magnetic sleeve body and the plastic fastener are fastened together, to achieve said magnetic connection structure, that is low in production cost and easy to install. In case the plastic fastener is damaged, it can be replaced readily.

Abstract: A foam soap dispenser capable of adjusting the amount of air includes a pump, piston rod, a valve seat sheathed on the piston rod, a feed pipe coupled to the pump, a feed check valve for feeding a foam soap and a discharge check valve installed in the pump, an air-liquid mixing chamber formed between the feed check valve and the discharge check valve, an air-intake pipe communicated with an air-liquid mixing chamber, and an air-intake hole formed on the air-intake pipe that connects the air-liquid mixing chamber. The air-intake pipe includes an air-intake check valve, a screw sleeve and an air adjusting screw rod. The screw sleeve is fixed to the air-intake pipe, and the air adjusting screw rod is fixed into the screw sleeve and passed through a through hole of the screw rod of the check valve to insert the screw rod into the air-intake hole.

Abstract: A foam soap dispenser includes a cylindrical external casing having two ports, a first check valve installed at a liquid soap inlet end of the external casing, an inner tube installed at a liquid soap outlet end of the external casing, a second check valve fixed to an inner end of the inner tube, a slide plug installed between the inner end of the inner tube and an inner wall of the external casing and slidable with the inner tube along the inner wall of external casing, a gap formed between the slide plug and the inner tube and covered by a soft edge of the second check valve, a vent hole formed at the external casing, and a chamber formed between the two check valves and communicated with outside air when the soft edge of the second check valve is not covered onto the gap.

Abstract: A water spray structure includes an outer housing, an inner sleeve, a mesh member, a spray member and an end cap. The inner sleeve is located in the outer housing. A gap is defined between an outer wall of the inner sleeve and an inner wall of the outer housing. The inner sleeve has apertures thereon. The spray member is located in the inner sleeve and has a plurality of through holes around a circumferential portion thereof. Each of the through holes has a large upper part and a small lower part. The spray member has stop pieces under the through holes. The stop pieces are disposed in a tangent direction. A mixing chamber is defined between a lower end of the spray member and a lower portion of the inner sleeve. The spray member has the plurality of through holes disposed around the circumferential portion of the spray member, the inlets and the transversal inlets to separate water to flow in the through holes. The stop pieces are disposed under the through holes to disperse the water in a spiral form.

Abstract: In one preferred embodiment, an apparatus for testing a cable includes an interface for connecting to a connector of the cable, many resistors, a socket, and a meter for testing resistance of the resistors. The interface has many pins, the resistors respectively connected to the pins in series, and the socket is electrically connected to the pins respectively via the resistors. The meter includes two probes, one of the probes is connected to another connector of the cable, and the other one of the probes is plugged into the socket. Because conductors of the cable are respectively connected to the resistors in series, the user can tell whether the cable has a fault according to the resistance indicated by the meter.
