Abstract: Embodiments of the present disclosure relate to multi-band FDD transceivers. An example transceiver includes a LO, configured to generate a LO signal to be shared between a receiver and a transmitter of the transceiver. Both the receiver and the transmitter use quadrature signal processing and are configured to multi-band operation. Sharing a single LO to perform frequency conversion of different frequency bands of received and transmitted signals advantageously allows reducing the number of LOs used in a multi-band FDD transceiver.

Abstract: A measuring wheel may include a wheel assembly comprising a first wheel and a second wheel, a handle operably coupled to a shaft, a housing to which the shaft and the wheel assembly are operably coupled, and a fixed stand disposed at a portion of the housing substantially between the first and second wheels.

Abstract: A hand truck having improvements made to simplify and make more ergonomically use of a hand truck by an operator. The hand truck provided having adjustable handles and a bottom portion having adjustable stair climbers with improved feature and an improved wheel and brake assembly have an axle-less wheel assembly and an improved caliper mounting system. These features are discussed in detail in the forgoing.

Abstract: A bullet loader method and apparatus that enables a user to easily load bullets into a gun magazine. The gun magazine is inserted into the apparatus magazine opening. Bullets are individually loaded into the bullet loader with a grooved cam, so that the individual bullets rest in the groove. The cam is rotated so that the bullet travels within the groove(s) of the cam and pushed with a cog attached to the end of the groove into the magazine. The bullet is pushed into the magazine with both a downward and inward force to overcome the spring resistance of the magazine.

Abstract: An apparatus for chemical mechanical planarization includes a spindle assembly structure and at least one substrate carrier, which make a linear lateral movement relative to each other while abrasive surfaces of a plurality of cylindrical spindles in the spindle assembly structure contact, and rotate against, at least one substrate mounted on the at least one substrate carrier. The direction of the linear lateral movement is within the plane that tangentially contacts the plurality of cylindrical spindles, and can be orthogonal to the axes of rotation of the plurality of cylindrical spindles.
