AI Technical Summary

Benefits of technology

This patent describes a technology that allows a device to detect vibration or shock and quickly alert other devices. The alert message includes information about the location where the vibration or shock was detected. The receiving device can then temporarily park its hard disk drive to prevent damage from the vibration or shock. This technology can improve the reliability and protect sensitive data in devices that are often subject to damage from vibration or shock.

Problems solved by technology

The number and types of mechanical parts, the rapid data response times, the very tight physical tolerances and the sensitivity of the ferromagnetic materials that are needed for a hard disk drive to function also make the hard disk drive more vulnerable to damage.
In particular, a hard disk drive can experience damage and data loss as a result of be subjected to vibration or shock.
Efforts to design vibration-resistant and shock-resistant mounting systems and enclosure are not able to prevent all types and magnitudes of vibration or shock.

working example 1

[0043]In reference to FIG. 6, commuters are on a train 150 on their way to work (see left-to-right direction of travel indicated by the arrow 152). The cars of the train are labeled C1-C5 from the front of the train to the back. The train 150 rides on a track 156 that includes a bump 154. As the train continues moving forward the cars will encounter the bump 154 in order. As shown, car C1 has already passed the bump 154, and car C2 is about to experience the bump. After that, the cars C3-C5 will encounter the bump 154 in sequential order and with a time delay according to the speed of the train and the length of each car.

[0044]FIG. 7 is a diagram of only cars C3 and C4 from FIG. 6. Two of the commuters (User 1“U1” and User 3“U3”) are using their laptops computers and one commuter (User 2“U2”) is using a mobile phone. U1 (laptop computer) and U2 (mobile phone) are in car C3 of the train 150, and U3 (laptop computer) is in car C4. As the train moves forward in the direction of the arr...

[0046]FIG. 8 is a diagram of a low flying jet 160 causing potentially damaging levels of vibration to devices along its path. The jet has already flown over a first device U1, resulting in U1 detecting the vibration and sending out a detection message (Detection Message 1), which identifies the time (Time 1) and physical location (Location 1) of the first device U1 at which the vibration was detected. Optionally, the detection message may further identify the duration of the vibration, if known. However, the detection message should be sent out immediately, such that the duration may not yet be determinable.

[0047]As shown, the second device U2 has just detected vibration and has also sent out a detection message (Detection Message 2), which identifies the time (Time 2) and physical location (Location 2) of the second device U2 at which the vibration was detected. The detection messages are communicated through the network 56, 58 to a server 100 (Vibration / Shock Detection and Alert M...

Abstract

A communication device includes a vibroscope or an accelerometer for detecting vibration or shock, a hard disk drive for storing data, and a wireless communication transceiver. In response to detecting vibration or shock, the communication device automatically broadcasts an alert message that identifies a physical location of the communication device at the time that the vibration or shock is sensed. In response to receiving an alert message from another communication device, the communication device automatically temporarily parks a read-write head of the hard disk drive to prevent damage from the vibration or shock.

Description

BACKGROUND[0001]1. Field of the Invention[0002]The present invention relates to systems and methods for protecting vibration-sensitive communication devices against damage during transient vibration or shock events.[0003]2. Background of the Related Art[0004]Hard disk drives are a common component of computer systems because these devices are able to store large amounts of data in a low cost and efficient manner without loss of data when power is turned off. For example, a modern hard disk drive may store multiple terabytes of data in a small form factor, such as 4 inches wide, 6 inches deep and only 0.8 inches thick.[0005]A typical hard disk drive has one or more disks or platters with a thin film of a ferromagnetic material. Data is stored as changes in the direction that the ferromagnetic material is magnetized. A read-write head is positioned close to the surface of the disk in order to modify magnetization of the material (i.e., write data) and detect magnetization of the mater...
