摘要:
A device for extending an event time of a physical shock imparted on an electronic device. The device includes a rigid or semi-rigid frame and a resiliently elastic material coupled to the frame, the resiliently elastic material suspending an electronic device with respect to the frame. The resiliently elastic material may be in the form of a sheet, a strap, a rib, and combinations thereof. One preferred resiliently elastic material is a polymeric material.

A system in one embodiment includes a disk; a reservoir having a selectively openable cover; a lubricant in the reservoir; and a sensor for detecting an event or condition that triggers opening of the cover. A method in another embodiment includes determining that a trigger event or a trigger condition is occurring or has occurred in a hard disk drive; opening a cover of a lubricant reservoir for allowing egress of lubricant therefrom upon determining that the trigger event or the trigger condition has occurred; and closing the cover of the lubricant reservoir after a period of time. Additional systems and methods are also presented.

A method and apparatus for determining the likelihood that a hard-disk drive (HDD) will experience an imminent error in operation is provided. The HDD comprises a differential pressure sensor capable of measuring the difference in the pressure between the interior and the exterior of the enclosure. The differential pressure sensor may reside in a breather filter covering an air passage within the enclosure. The HDD also comprises a risk assessment component capable of (a) determining an expression of how likely it is that the HDD will experience an imminent error in operation based, at least in part, upon the difference in pressure measured by the pressure sensor, and (b) communicating the expression to a user of the HDD. The HDD may optionally comprise one or more of an atmospheric pressure sensor, a particle counter, and a chemical vapor sensor which may be used by the risk assessment component.
摘要:
A device and system for monitoring the condition of an electrical outlet such as a 110 volt or 220 volt outlet to alert a user to a dangerous situation and to interrupt power to the circuit in the event of the dangerous condition. The device monitors the circuit for degradation to the electrical outlet. The system can include a temperature sensor voltage meter or particle detector (smoke detector) connected with a power outlet. When a parameter of a circuit exceed a predetermined level (indicating the outlet has degraded to an unsafe level) a warning can be reported and if necessary power to the device can be adjusted or interrupted.
摘要:
A composite disk-clamp assembly including a clamp or spacer of a resilient material coupled to a disk by injection molded plastic so that the clamp forms an integral portion of the disk itself.
摘要:
An assembly for coupling a disk to a spindle includes a lower layer adapted to engage the disk and an upper layer constructed of a material having a stiffness greater than that of the lower layer. The upper and/or lower layer has protrusions extending therefrom for mating with receiving areas of the other layer.

A device for monitoring lubricant within a disk drive includes a reservoir packet impregnated with lubricant. The reservoir packet is disposed between a first metal screen and a second metal screen such that a lubricant reservoir transducer is created. The capacitance of the lubricant reservoir packet is monitored and when it falls below a predetermined percentage of the initial capacitance, a user is warned to back up the files contained in the disk drive before failure due to lack of lubricant occurs.
摘要:
An assembly for coupling a disk to a spindle includes an annular spacer ring adapted to engage the disk and an annular clamp. The spacer ring is constructed at least in part of a plastic material. The clamp is constructed of a material having a modulus and stiffness greater than that of the spacer ring.

摘要:
The present invention is a magnetic disk drive for reading or writing magnetically, comprising: (i) a base plate; (ii) one or more of magnetic disks; (iii) a hub fixedly attached to the disks for supporting the disks; (iv) a motor operable to rotate the hub; (v) one or more of magnetic read/write heads, each associated with the surface of a disk; (vi) an actuator for supporting the heads and moving the heads across the disks; (vii) a support shaft attached to the base plate; and (viii) a load/unload structure for displacing the heads from the disk comprising an elongated body, a base portion fixedly attached to the base plate and a plurality of ramps extending outwardly from the body. The body of the structure is mounted through one or more holes in the body onto the support shaft so that the support shaft extends along the length of the body to support the structure.
