摘要： A shock absorbing racket structure comprising a head frame, a handle, and a pair of yoke bars connecting the head frame to the handle. Wherein, the yoke bars are hollow tubular members extending through the handle to a butt plate, forming a pair of cylindrical chambers within the handle. Within each cylindrical chamber is lodged a bullet-shaped resilient body, from which extends an axial rod, on whose rear termination is attached a support plate common to both axial rods and backed by the butt plate.

摘要： Systems and methods for creating a mixed ringtone for a personal device. A user accesses a server, including a template selector and selects a template into which a user-created recording may be mixed. The user then records a recording, which is used by the server in association with the selected template to produce a mixed ringtone. The mixed ringtone is then formatted for the user's device and transmitted to the user's device.

摘要： A method for overcoming a stiction condition in a disk drive is disclosed. In one embodiment, the method includes the steps of: (1) providing a plurality of disks each having a pair of disk surfaces, each of the disk surfaces having a corresponding actuator arm assembly including a head; (2) providing a spin motor for rotating said plurality of disks when a stiction condition does not exist; (3) providing a voice coil motor for positioning said heads relative to said disk surfaces when a stiction condition does not exist; (3) providing a microprocessor for controlling application of a voice coil motor current to said voice coil motor and for controlling application of a spin motor current to said spin motor; (4) applying a spin motor current to said spin motor; (5) sensing that the spin motor is not rotating said plurality of disks and, hence, a stiction condition exists; (6) applying a first oscillating current to said voice coil motor in response to said stiction condition, said first oscillating current having a fixed frequency and a first amplitude; (7) determining whether said spin motor is rotating in response to said first oscillating current; and, (8) continuing to apply said first oscillating current for at least one commutation state of said spin motor after determining that said spin motor is rotating in response to said first oscillating current.

摘要： A shock absorbing racket comprises a head frame, two connecting protrusions, a yoke portion, and a handle. Extending outwardly from the bottom of the head frame, two connecting protrusions integrate with the yoke portion. The racket handle has a portion adjacent the juncture which is defined as the yoke portion. Respective to each other, two pairs of grooves are disposed around the outer peripheries of the two connecting protrusions at a suitable distance adjacent the juncture. Two recesses are disposed around the outer periphery of the yoke portion. The handle is wrapped by a shock absorbing band. Each recess is enclosed by an elastic shock absorbing member respectively. Each groove is tied by a shock absorbing fillet respectively.
