摘要： A lock for door includes a locking latch assembly, a lock rotor, a lock bolt and a rotating member, wherein the latch includes an upper rotor member, a clutch transmission set, a deceleration gear set, and a motor. When the deceleration gear set is driven by the motor, the deceleration gear set immediately drives the clutch transmission set to move the lock bolt. When the lock rotor is manually driven to rotate and the upper rotor member is connected to rotate, the upper rotor member pushes the clutch transmission set for a clutch action, so that the clutch transmission set only drives the lock bolt to move so as to selectively lock and unlock the lock for door.

摘要： A lock includes a latch assembly, a first locking mechanism, a second locking mechanism, a linkage mechanism, a clutch mechanism, and a rebounding mechanism. The lock utilizes a first clutch member and a second clutch member of the clutch mechanism to coordinate with a leaning portion of an inner linkage member of the linkage mechanism to achieve that when the turned inner linkage member will outward push the first clutch member and the second clutch member away from each other to make the second clutch member rapidly and accurately be engaged with an outer linkage member of the linkage mechanism so as to make the outer linkage member to drive the latch assembly to unlock. The arrangement provided by the present invention that has the first clutch member and the second clutch member coordinate with the leaning portion of the inner linkage member simplifies the entire structure of the lock.

摘要： An electronic lock structure using a wireless charging device contains: a power supply unit and an electronic lock unit. The power supply unit includes a variable-frequency drive and an AC/DC transformer. The electronic lock unit includes a battery and a rectification circuit, wherein the rectification circuit electrically outputs power of alternative current by way of a power receiving coil. When the power receiving coil is close to the power output coil, the power supply outputs the power to the electronic lock unit by using magnetic flux and to supply the power to the battery, thus charging the battery. When the power receiving coil is away from the power output coil, the power output coil does not conduct the power to the power receiving coil.

摘要： Systems and methods electrically connect a first electronic device or electrical component, having a external electrical connector, to a circuit board of a second electronic device. A low-cost, user-installable connection system isolates mechanical stresses imposed on the external electrical connector to within the user-installable connection system, thereby preventing the mechanical stresses from reaching the circuit board in the second electronic device. If the connection becomes faulty, only the low-cost, user-installable connection system must be replaced.

摘要： A control module for a multi-nozzle shower has a body, a control panel and a controlling assembly. The body is mounted securely in the shower and defines at least one chamber having valve seats, at least one inlet and multiple outlets respectively communicating with the nozzles. The control panel is mounted securely on the body and seals the at least one chamber. The controlling assembly is mounted in the control panel and has multiple valve disks and buttons. The valve disks selectively block the valve seats to stop water flow. The buttons connected to the valve disks and are arranged on the control panel and selectively actuate the valve disks to block the valve seats. Thereby, people can conveniently control water discharged from different nozzles or showerheads of the shower.

摘要： Described embodiments relate to improved methods and systems for computationally efficient optimization of radiation dose delivery. The optimization involves determining an improved form of objective function to be used for mapping radiotherapy beams to a patient body volume having at least one target volume and at least one non-target volume. The objective function has a first term related to the at least one target volume and a second term related to the at least one non-target volume. The optimization further involves determining a minimum of the objective function, whereby beams, comprising a plurality of beamlets, mapped to pass through the at least one non-target volume, comprising a plurality of non-target volume portions, are limited such that the second term is zero only if, a product of the intensity of a beamlet mapped to pass through a non-target volume portion and the dose deposited by said beamlet is equal to a first predetermined average dose constraint value for the respective non-target volume portion, for all beamlets mapped to pass through the at least one non-target volume. This limit aims to reduce the occurrence of negative beam weights, thereby facilitating computationally efficient determination of the minimum of the objective function and achieving more physically realistic beamlet intensities. In another embodiment, the objective function has a smoothing term for biasing the intensity of beamlets, for a respective beam mapped to pass through the at least one target volume and the at least non-target volume, towards a uniform distribution within the respective beam. Following the optimization, radiotherapy is delivered based on the determined minimum of the objective function.
