A wireless communication device is configured to provide wireless communication to a host device when disposed in a mated position with the host device such that a housing of the wireless communication device extends a distance Lid from a face of the host device. The wireless communication device includes a transceiver, a controller in communication with the transceiver, and a modem in communication with the controller. The wireless communication device also includes a dipole antenna having a dipole effective current axis Ix for a selected wavelength λ in the mated position that is at a distance from the face of the host device that is in the range of about 0.09λ to about 0.25λ.

A structural improvement of the canned pump is to improve the stiffness of a stationary shaft and, according to requirement, to dispose a monitor device. The method for improving the stiffness of the stationary shaft includes axially inserting a shaft metal rear support of the metal structural of a motor rear casing of a canned motor into the inner side of a rotor yoke of an inner rotor of the canned motor, tightly attaching the shaft metal rear support to a rear shaft seat for improving the stiffness of the stationary shaft by longer hold length, and for shortening an arm length of the composite force. The monitor device, used for detecting the wear of a bearing for enhancing the reliability and satisfying the driving requirement, is installed in the ring slot to be protected by the rear shaft seat.

A site light includes a body, an arm coupled to the body having an adjustable arm length, a light assembly coupled to the arm opposite the body, and a drive mechanism with a crank arm rotatable about a first axis. Rotating the crank arm in a first direction causes the arm length to increase. Rotating the crank arm in a second direction causes the arm length to decrease. The drive mechanism is adjustable between a first configuration, where the crank arm can only rotate in the first direction, and a second configuration, where the crank arm can be rotated in the first direction and the second direction.

The invention provides a harmonic reducer with a short barrel-shaped flexible wheel. A wave generator is arranged in an inner hole of the flexible wheel (18), and outer teeth of the flexible wheel (18) are engaged with inner teeth of a rigid wheel (6); the rigid wheel (6) is fixedly connected to a spigot inner hole of a housing (16) through a pin (8), a spring gasket (19) and a bolt (20); the flexible wheel (18) and a low-speed shaft (15) are fixedly connected together through a bolt (10) and a spring gasket (11); the wave generator and a high-speed shaft (1) are fixedly connected together through a key (9), and are axially positioned through a shaft elastic retainer ring (3); finally, a bearing (2) and a bearing (12) are arranged at the two ends of the high-speed shaft (1) respectively, so that the wave generator realizes axial positioning motion and radial positioning motion; the high-speed shaft (1) and the low-speed shaft (15) realize linear coaxial transmission. The harmonic reducer disclosed by the invention is reduced in size and weight, and can be used for realizing relatively large torque transmission output.

The invention relates to an all-optical logic gate with a Michelson structure, which can be reused for realizing an AND gate, an OR gate, an NOT gate, an NAND gate, an NOR gate, an XOR gate and an XNOR gate as well as the reverse operation thereof, and also realizing a half-adder. The all-optical logic gate with a Michelson structure comprises two control optical signals, a synchronous optical detection signal and an output detection signal, wherein the two control optical signals are input into an arm (2) of symmetrical Michelson interferometers by a coupler (1); the synchronous optical detection signal is divided into two beams of equal light to be projected into the arm (2) and an arm (3) of the Michelson interferometers and used for outputting a reflecting output opening (4) for expressing the application of the logic result and a transmitting output opening (5) of the reverse operation; the output detection signal is results of the self-phase modulation of a detection optical signal, the intersection phase modulation of the two control optical signals on detection light and average intersection phase modulation on the detection light in two times of arm length and is expressed into a corresponding logic gate relation. The all-optical logic gate has the characteristic of self-phase modulation in the symmetrical Michelson interferometers, preferably the two arms adopt different nonlinear optical fibers and the input arm (2) of the control optical signals adopts a high nonlinear optical fiber.

The present invention relates to a bandage that is designed for use preferably on a digit of a person's foot but that may also be used on the digit of a person's hand or other similar surfaces. In particular, the bandage comprises a body having at least a first side surface, a second side surface, a first end, and a second end. The bandage is designed to have adjustable arms at each of the first and second end so that an arm may be adjusted if it is difficult to wrap the respective arm around the anatomical digit and/or in between the spaces of the anatomical digits.

The invention provides a balanced arm (201) for transferring a fluid product, having a transfer compass comprising an inner transfer member (208) and an outer transfer member (221), articulated together, and a counterweight system (203) for balancing the transfer compass, characterized in that the compass is installed on a turntable (215) rotatable about a vertical axis, to rotationally drive the transfer compass about that axis, and the balancing system comprises at least one counterweight (207; 207′) mounted so as to be able to turn about an axis (206) of horizontal general orientation, on a support (251) fixed to the turntable and functionally linked to the inner transfer member to provide the balancing of the transfer compass.
