摘要： Methods in intermediate frequency and direct conversion receivers for reducing pre-selection filter leakage and harmonic coupling to a programmable voltage controlled oscillator by mixing a receive signal at a mixer having a mixer injection frequency outside a pre-selection filter passband. In some applications, the mixer injection frequency is conditionally moved outside the pre-selection filter passband. In other applications, signal gain is increased to compensate for any loss resulting from shifting the mixer injection frequency outside the pre-selection passband.

摘要： A vertebral disc including a superior surface layer, an inferior surface layer, a midsection between the superior and inferior surface layers and a hollow center. The superior surface layer and inferior surface layer each comprise a layer of lattice with pore sizes in the range of 200-900 μm and a porosity of each layer of 55-75%. The midsection of the implant comprises a random or pseudorandom lattice interposed between the superior surface layer and inferior surface layer with larger, macro-pores of various sizes. There is a gradient of pore sizes along a longitudinal axis with the smallest pore sizes comprising the superior and inferior surfaces and the largest pore sizes comprising the midsection.

摘要： A Personal Area Network (PAN) (100) including multiple communication devices (104, 106, 108) is provided. The communication devices are capable of communicating with each other and a connection point. The communication devices derive energy from multiple fuel cells (110, 112, 114). The PAN is capable of distributing fuel to the multiple fuel cells from a common fuel container (116), if the communication devices are attached to the connection point.

摘要： Disclosed herein is a method and apparatus for inductively charging a battery. The battery comprises a housing (102), at least one battery cell (104) carried in the housing and a multimode near field transceiver (106) carried also in the housing. The near field transceiver is operable in a passive mode to provide information and active mode to exchange information. The battery further comprises a charging coupler (108) coupled to the cell through a charging circuit (110) and a communication coupler (112) or antenna coupled to the transceiver.
