International Classification:

H04N 3/08

US Classification:

348203, 348 90, 348 96, 348 98, 348195, 348206, 348202, 348264, 348792, 348744, 372 3802, 3591961, 359198, 359199, 359848, 359871, 358408

Abstract:

Briefly, in accordance with one or more embodiments, a scanner for a scanned beam display may comprise a scanning platform having a mirror disposed thereon to reflect a beam of light impinging on the mirror, a drive coil disposed on the scanning platform to scan the reflected beam of light in response to a drive current applied to the drive coil. The drive coil has coil winding segments having a narrower width in one or more regions of the drive coil, and has coil winding segments having a greater width in one or more other regions of the drive coil to provide a the drive coil with a reduced electrical resistance.

International Classification:

G02B 26/08

US Classification:

3592241

Abstract:

A microelectromechanical system (MEMS) includes a conductor with improved reliability. The conductor flexes with a moving member in the MEMS device, and the improved reliability is achieved through material selections that provides increased fatigue resistance, reduced crack propagation, and/or mechanisms for improved live at a given strain level. The conductor may include a single material, or may include layers of different materials.

International Classification:

G02B 26/08

US Classification:

3592007, 3592241

Abstract:

A magnetically actuated system includes a conductor and a magnetic field apparatus to generate a magnetic field. The magnetic field apparatus includes magnets and magnetically permeable materials to focus the magnetic field in areas of the conductor that produce a drive torque when the conductor carries a current.

International Classification:

G06F 17/30

US Classification:

707698, 707697, 707E17001

Abstract:

A resilient hashing system leverages a fast, non-cryptographic hash/checksum function that has good diffusion properties while remaining reasonably efficient on modern central processing units (CPUs). The hash function uses random secret data so that hash keys for particular data are difficult to predict. Due to its internal structure, well-chosen random secret data is difficult for an attacker to counter without having access to the direct output of the hash function. At every stage of the block function, there are at least two operations that can be performed in parallel, increasing performance on modern superscalar CPUs. Thus, the resilient hashing system provides a hash table and checksum that can be used in Internet-facing or other vulnerable sources of input data to manage performance in the face of malicious attacks.

H04N 9/31
G03B 21/00

Abstract:

A mechanically resonant system exhibits a resonant mode frequency response. A conductor is included on a resonant member within the mechanically resonant system. A current in the conductor causes a modification of the resonant mode frequency response when in the presence of a magnetic field. The modification of the resonant mode frequency response may include an offset in the natural frequency of the mechanically resonant system.
