Method Of Fabricating Optical Device Using Multiple Sacrificial Spacer Layers

Patent Identifier: 
RE45084

The present invention is a method of fabricating an optical device using multiple sacrificial spacer layers. The first step in this process is to fabricate the underlying base structure and deposit an optical structure thereon. A facet is then created at the ends of the optical structure and alternating sacrificial and intermediate layers are fabricated on the device.

Photoacoustic Joulemeter Utilizing Beam Deflection Technique

Patent Identifier: 
8711342

A joulemeter is capable of non-destructively measuring multiple characteristics of a laser beam. The joulemeter comprises a series of parallel probe beams, which are directed though a transparent media adjacent to an absorbing media that the tested beams pass through. Arrays of optical sensors or a chirp sensor are used to intercept and measure deflections the probe beams.

Ais Demodulator For Unknown Carrier Phase And Baud Alignment

Patent Identifier: 
8665997

A method of demodulating an AIS signal by receiving the signal, sampling the signal, estimating the carrier frequency, estimating the complex conjugate of the carrier frequency contribution to each sample, multiplying each sample by the complex conjugate and calling the results a base-banded sampled signal (BBSS), correlating the BBSS with known preambles, identifying a maximum magnitude of the

Method Of Image-Based User Authentication

Patent Identifier: 
8655027

A method of authenticating a user by capturing an image of the user, assigning a user-name, selecting an image category, selecting a pattern, selecting locations on the user's face, assigning a rotation-value, logging onto a computer, presenting images, where some images are in the image category, selecting images that are the pattern away from the images in the image category, calculating

Device For And Method Of Detecting Sim Card Removal And Reinsertion

Patent Identifier: 
8478340

A device for and method of determining if a SIM card was removed and reinserted into a device by initially inserting the SIM card into the device, checking for the presence of the SIM card, if the SIM card is present then returning to the second step, if the SIM card is not present then reporting that the SIM card has been removed from the user-definable electronic device, checking for the pres

Usb Port Protector

Patent Identifier: 
8449309

A Universal Serial Bus port protector having a top piece and a tongued planar surface, where the top piece includes a rectangular surface, a rectangular planar surface, a box having an open bottom and an open top, and a shim-like piece, and where the tongued planar surface includes a tongued portion and an untongued portion, where the tongued portion includes one dado and two rabbet cuts and tw

Single-Use Usb Port Protector

Patent Identifier: 
8414314

A single-use Universal Serial Bus port protector having a top piece and a tongued planar surface, where the top piece includes a rectangular surface, a rectangular planar surface, a slotted planar surface, and at least one lever breakably attached to the slotted planar surface, and where the tongued planar surface includes two rails and two projections, where the top piece and the tongued plana

Infinite Impulse Response Resonator Digital Filter

Patent Identifier: 
8396912

The IIR resonator digital filter which is the subject of this patent invention comprises a first register having a plurality of inputs and outputs, a multiplexer/demultiplexer having a plurality of inputs and outputs, a first multiplier having a plurality of inputs and an output, a second multiplier having a plurality of inputs and an output, a third multiplier having a plurality of inputs and

Coherent Demodulation Of Ais-Gmsk Signals In Co-Channel

Patent Identifier: 
8275077

The present invention pertains to demodulation of GMSK signals by estimating a carrier frequency of the signal having a carrier residual, basebanding the signal, tracking the signal's carrier frequency, removing the carrier residual, detecting a data burst, generating a bank of poly-bit matched filters, applying the bank of poly-bit matched filters to the signal, determining a magnitude an

Device For And Method Of Making Element Appear In Shortest Network Path By Minimal Decrements And Increments

Patent Identifier: 
8233397

A device and method of minimally incrementing and decrementing the weights of a minimal number of links in a network to cause a link/node that is not in the shortest path in the network to be in the shortest path by determining the shortest path with link/node, identifying links in this path that are not in the shortest path without link/node, decrementing identified links to make the path the
