摘要:
Limiting the sound pressure level presented to the listener's ears by one or more headphones, using processing capabilities of a personal media device. Headphones, coupled to audio signals from a personal media device, include a sensor to measure the sound pressure level presented to the listener's ears, and provide that measure to the personal media device. The personal media device, optionally aided by one or more analog circuits, adjusts the audio signal so that the sound pressure level is maintained within a recommended range.

Various aspects of this disclosure are directed to an earphone device comprising a speaker unit including at least one balanced armature transducer to convert an electrical signal into an acoustic signal. The electrical signal may define a frequency range comprising a first frequency and a second frequency. The earphone device may further comprise an impedance correction unit configured to receive the electrical signal and compliment an impedance of the speaker unit such that a sum of an impedance of the impedance correction unit and the impedance of the speaker unit at the first frequency is substantially similar to a sum of an impedance of the impedance correction unit and the impedance of the speaker unit at the second frequency.

A portable desktop device and method for host computer system hardware recognition and configuration are provided. The portable desktop device once authenticated provides access to a portable desktop application that provides a beat signal to the portable desktop device. In an absence of the beat signal, the portable desktop device prevents access to the portable desktop application and/or data associated therewith.

A removable media device, which may be a USB attached device or other type of removable media device, includes a software program located on the device which upon startup or access, the software program scans one or more of electronic files stored on the removable media device and electronic files being transferred to or from the electronic media device and to or from a host computing system for the detection of viruses therein. The software program is further configured to block the transfer of detected virus-containing electronic files and to disallow the copy or writing of files to or from the removable media device to or from a host computing system that can not be scanned. The software program is further configured to block the encryption of files being written to a removable media device if such device contains hardware or software encryption if such files can not be scanned.

A method for transmitting digital data to a recipient via a communications network includes providing digital data and digitally signing the digital data using N cryptographic keys. Each of the N cryptographic keys is associated with a same sender of the digital data, and N>1. The recipient receives the digital data and verifies the digital signature using N cryptographic keys associated with the N cryptographic keys used to sign the digital data. In dependence upon verifying the digital signature, the recipient accepts the digital data as being authentic.

A method comprises generating first and second magnetic field components in a magnetic medium, the second magnetic field component substantially opposite the first. A pattern is written onto the magnetic medium, and a signal is generated by reading the pattern. The magnitude of the second magnetic field component is controlled based on an asymmetry of the signal.

A system comprises a first tapered core configured for positioning adjacent a first surface of a magnetic medium, and a second tapered core configured for positioning adjacent a second surface of the magnetic medium, opposite the first tapered core along a travel direction of the magnetic medium. Each of the first and second tapered cores has a transverse width defined with respect to the magnetic medium, where the transverse width decreases from a first end of the tapered core to a second end of the tapered core, the second end forming a pole face adjacent the magnetic medium.

A method for making memory more reliable involves accessing data stored in a removable storage device by translating a logical memory address provided by a host digital device to a physical memory address in the device. A logical memory address is received from the host digital device. The logical memory address corresponds to a location of data stored on the removable storage device. A physical memory address corresponding to the local address is determined by accessing a lookup table corresponding to the logical zone.
摘要:
A system comprises a magnetic medium with a first magnetic gap adjacent a first side and a second magnetic gap adjacent a second side, opposite the first magnetic gap. The first magnetic gap generates first longitudinal and perpendicular field components. The second magnetic gap generates second longitudinal and perpendicular field components. The first and second longitudinal field components are substantially aligned along a recording layer of the magnetic medium, and the first and second perpendicular field components are substantially opposed across the recording layer of the magnetic medium.

Bootability of a computer system with multiple LUNs. A flash device powers-on into a default LUN, from which the system boots, maintaining any other LUNs unavailable. The first LUN reconfigures the system to remove itself as the available LUN, to load a second LUN as the only available LUN, and to reboot the computer system into the newly available second LUN. The second LUN reconfigures the system to load any additional LUNs, such as removable storage on the flash drive. Upon reconfiguration, the system includes multiple LUNs. The second LUN includes an interpolated LUN driver, which exposes additional LUNs before operation of other device drivers. The interpolated LUN driver takes control during boot-up, exposing any available LUNs before the regular environment's operating system.
