A golf club putter head includes a faceplate groove pattern configured to provide the putter head with an elevated center of gravity. In one preferred form, a club head body defines a faceplate having at least one and preferably multiple elongated grooves formed therein to extend generally in a heel-to-toe direction, with at least one groove positioned above a vertical mid-point of the club head body. The groove depths progressively increase in a top-to-bottom direction so that the putter head center of gravity is elevated to a position spaced above the vertical mid-point of the club head body. When striking a golf ball, the elevated center of gravity functions to minimize initial ball skidding and to promote early smooth ball roll toward a target such as a cup on a golf green.

A multibeam transmitting / receiving apparatus is provided that is capable of increasing the accuracy of a direction in which a transmission beam is to be transmitted, with a simple arrangement. Signal power measuring units (8-1 through 8-L) of signal processing means (40-1 through 40-L) measure reception signal power levels averaged over a given time, using outputs from reception beam formers (5-1 through 5-L), and indicate the measured reception signal power levels to transmission antenna weight generator (30). Transmission antenna weight generator (30) generates transmission antenna weights, which has been weighted by a reception signal level, from a transmission antenna weight corresponding to reception signal power level P1 and a beam number B1 of a finger having a maximum reception signal power level, and a transmission antenna weight corresponding to reception signal power level P2 and a beam number B2 of a finger having the same path timing as the finger having the maximum reception signal power level. The generated transmission antenna weights are used in transmission beam former (16).

A control unit 6 obtains position data from a sensor unit 1 to specify the position of the main body of an apparatus, and also obtains acceleration data from the sensor unit 1 to specify the azimuth along which the main body faces forward. Then, the control unit employs the azimuth data and the position data to calculate distance data and directional data relative to a predesignated or given position, and outputs these data as sound localization data. Based on the sound localization data, a processing unit 7 performs a stereophonic sound process for digital audio data, and generates digital audio data having directivity. A conversion unit 8 converts the digital audio data into analog audio data, and drives loudspeakers 9 and 10 to release stereophonic speech. As a result, using a speech form that is easily understood simply by listening, a direction instruction can be provided for a listener.

The putter disclosed herein has an aiming mark at an oblique angle that compensates for a player's misalignment of the putter with the aimline or for putter twisting during the stroke. The face has friction and energy transfer characteristics that correct for errors in club face orientation or for directional errors in stroking the putter. The putter can be configured with a weight distribution that causes the compensations to vary with stroking force. The aiming mark, the face characteristics and the weight distribution compensations may be combined in different proportions depending on a player's stroking errors.

Disclosed are a processor and a processing method incorporating an instruction pipeline with direction prediction (i.e., taken or not taken) for conditional branch instructions. In the embodiments, reading of a branch instruction history table (BHT) and a branch instruction target address cache (BTAC) for branch direction prediction occurs in parallel with the current instruction fetch in order to minimize delay in the next instruction fetch. Additionally, direction prediction is performed in the very next clock cycle based either on an initial direction prediction for the specific instruction, as stored in the BHT, or, if applicable, on a prior entry for the specific instruction in the BTAC. An override bit associated with each entry in the BTAC is the determining factor for whether or the BTAC or BHT is controlling. Override bits in the BTAC can be pre-established based on the branch instruction type in order to ensure prediction accuracy.

The wood or iron golf club has a reduced shaft width transverse to the direction of motion and a greater shaft depth parallel to the direction of motion, therefore, has a reduced frontal area that creates less aerodynamic drag and a higher resistance to bending opposite the direction of motion, respectively. The low drag rigid shaft allows higher head velocity, higher momentum transfer to the ball, higher ball velocity, and longer more accurate drives then current clubs with elongated cone shaped symmetrical shafts.The wood or iron gulf club shaft-head configuration has the shaft axis intersecting the common axis of the horizontal component of the line of play and the head center of gravity. The club therefore does not create a torque about the shaft axis during the swing motion or ball impact and facilitates greater accuracy and consistency in hitting the optimum point on the ball with the optimum point on the club head.
