Apparatus and associated systems and methods may relate to a wide bandwidth cable assembly that may include an active amplification stage to receive high frequency signals through a transmission line extending distally to a passive, high density signal probe stage. This liquid crystal composition has high dielectric constant anisotropy and low rotational viscosity, and is thus suitably used as a liquid crystal composition for IPS liquid crystal displays or low voltage-driven TN liquid crystal displays. When the optical sheet deforms with heat, the elastic adhesive member may be expanded or contracted corresponding to deformation of the optical sheet and absorb impact applied to LCD device. Each of projections is extended from the first contact piece so as to oppose the second contact piece, and is formed with a slant face so that a thickness thereof is reduced toward a distal end thereof. A digital processing circuit processes the digital samples so as to identify the time allocation and to recover the downlink data transmitted during the identified time allocation, while shutting down the RF receiver during at least one interval during the downlink frame that is outside the identified time allocation. The metal golf club head comprises a hollow body with a weighting port.
