A load arm for a disk drive may include a base section that has an opening for receiving a spindle of a voice coil motor. The base section may have hinge arms that extend from the base section and terminate in tab portions. An arm section may be affixed to the tabs of the hinge arms of the base section such as by spot welding. A head suspension assembly may be affixed to a distal end of the arm section such as by spot welding. A sensor may be provided on a hinge arm of the base section. The sensor may comprise a piezoelectric polymer sensing element and an electrode formed over the piezoelectric polymer sensing element.

A disk drive includes a drive circuitry, a storage disk and a slider. The storage disk has a data surface, and the slider magnetically interacts with the storage disk to transmit a signal between the storage disk and the drive circuitry. The slider includes a leading surface, an opposed trailing surface, a data transducer positioned near the trailing surface, and a piezoelectric element. The piezoelectric element receives a driving voltage from the drive circuitry to adjust a distance between the data transducer and the data surface. The piezoelectric element can form a portion of the trailing surface. The slider includes a slider body that forms a portion of the trailing surface, and a portion of the piezoelectric element can be coplanar with the portion of the trailing surface formed by the slider body. Further, at least a portion of the piezoelectric element can be constrained by the slider body. The piezoelectric element can include an exposed surface that is substantially parallel with the leading surface. The slider body can have an element cavity that completely receives the piezoelectric element. In one embodiment, the piezoelectric element has only one substantially planar exposed surface.

A game controller operates in both a wired mode and a wireless mode, and is able to switch between these two modes without permanent disruption to an ongoing game. The game controller is configured to detect a condition that suggests switching from the wireless mode of operation to a wired mode of operation, convey the indication to a host game system, and transition from the wireless mode of operation to the wired mode of operation.
摘要:
A game controller operates in both a wired mode and a wireless mode, and is able to switch between these two modes without permanent disruption to an ongoing game. During a transition from one mode to another, a host gaming system detects when the controller is physically disconnected (for wired mode to wireless mode) or connected (for wireless mode to wired mode). Upon detection, the host gaming system stores the game data and user information and the game controller stores an identifier in its nonvolatile memory. The host gaming system and game controller then establish a new communication link. The game controller retrieves the identifier and submits it to the host gaming system, which uses the identifier to reassociate the game data and user information with the game controller as it begins operating in the new mode. This allows the player to continue game play without interruption.

Systems and methods for controlling the rise and fall times of USB signals for USB devices and peripherals are provided. The rise and fall times of USB peripherals can be controlled, or changed, in order to match the electrical characteristics of the USB peripheral to a USB host. By sweeping through a range of rise and fall times, and testing the reliability of USB output, optimal rise and fall times for the characteristics of a USB peripheral can quickly be determined. In one embodiment, the controllability of the rise and fall times is provided in firmware that changes at least one characteristic of the USB peripheral that affects the amount of current flowing during USB signaling.

The present invention relates to a sampler for gas hydrates by hole bottom freezing, the sampler comprises a fisher, a wire-line coring mechanism and an outer barrel, and it further comprises a refrigeration portion, a low temperature control portion and a frozen insulation sample portion, which constitute an inner barrel assembly located inside the outer barrel together, wherein a refrigerant in the refrigeration portion is injected into the frozen insulation sample portion under a control of the low temperature control portion, so that a cooling medium in the frozen insulation sample portion is always kept under a predetermined temperature, and a core sample of gas hydrates is frozen at the bottom of a drill hole. The invention also relates to a sampling method using the sampler as mentioned above. In the invention, the temperature of the sample can be decreased by using an external cooling source to suppress hydrate decomposition, the critical decomposition pressure of gas hydrates can be reduced by active decreasing the temperature of the sample, and the stability of gas hydrates is maintained by a passive pressure drop. The method of the present invention need not to keep the pressure of the sample, and is simple to obtain a core sample of gas hydrates with higher fidelity.

A massaging device with a variable surface for providing a good general massage that includes one user support surface (1), a structural support frame (2) and at least one dimensionally varying device (3). In one embodiment, the dimensionally varying device may be an airbag. At least one airbag is situated in between the user support surface and the structural support frame. The airbag utilizes a fluid that is either liquid or gaseous in nature to vary its dimensions. By the varying the dimensions of the airbag, the massage forces experienced by a user is indirectly varied. This embodiment can be used in a chair, bed or any other surface that is in contact with a user for the purposes of a massage. It may further include a pressure regulator for the fluid and force detection sensors so as to provide real-time feedback to the user as the massage progresses.
