Publication number: 20170111665Abstract: Delivering a content stream within a content delivery network (CDN) includes recording the stream using a recording tier, and playing the stream using a player tier. For a live stream, recording the stream begins when the stream is received at a CDN entry point in a source format. The stream is then converted into an intermediate format (IF), which comprises a stream manifest, a set of one or more fragment indexes (FI), and a set of IF fragments. A player process begins when a requesting client is associated with a CDN HTTP proxy. In response to receipt at the HTTP proxy of a request for the stream, the HTTP proxy retrieves the stream manifest and at least one fragment index. Using the fragment index, the IF fragments are retrieved to the HTTP proxy, converted to a target format, and then served in response to the client request. Preferably, fragments are accessed, cached and served by the HTTP proxy via HTTP.Type: ApplicationFiled: December 26, 2016Publication date: April 20, 2017Inventors: Babu Suryanarayanan, Ronnie So, Mihar Parikh, Ashok Jaiprakash Lalwani, Abdul Salam Faisal Padinjareveetil, James Egerton

Patent number: 9532092Abstract: A method and apparatus for delivering a content stream is implemented within a content delivery network (CDN) and, in one embodiment, includes the high level functions of recording the stream using a recording tier, and playing the stream using a player tier. For a live stream, the step of recording the stream includes a set of sub-steps that begins when the stream is received at a CDN entry point in a source format. The stream is then converted into an intermediate format (IF), which is an internal format for delivering the stream within the CDN and comprises a stream manifest, a set of one or more fragment indexes (FI), and a set of IF fragments. The player process begins when a requesting client is associated with a CDN HTTP proxy. In response to receipt at the HTTP proxy of a request for the stream or a portion thereof, the HTTP proxy retrieves (either from the archive or the data store) the stream manifest and at least one fragment index.Type: GrantFiled: December 30, 2010Date of Patent: December 27, 2016Assignee: Akamai Technologies, Inc.Inventors: Babu Suryanarayanan, Ronnie So, Mihir Parikh, Ashok Jaiprakash Lalwani, Abdul Salam Faisal Padinjareveetil, James Egerton

Publication number: 20160013477Abstract: A higher capacity nanoporous silicon thin film structure with alternating layers of silicon nanoparticles and carbon nanotube nonaligned will result in an anode for lithium ion batteries. This nanocomposite structure will increase the specific capacity to 3500 mAh/g-1 versus 350 mAh/g-1 for state of the art lithium batteries. Charge/discharge cycles of 5000 with a maximum of 15% loss are also achievable. This is due to the silicon nanocomposites capability to accommodate the mechanical expansion of the lithiated silicon species. Reliability defects such as copper cracking and delamination will be minimized using a barrier/adhesion metal layer. This will also reduce copper dendrite formation. Particle cracking and lithium plating will also be reduced by using the silicon based nanocomposite. The silicon nanocomposite can be fabricated using off the shelf deposition techniques minimizing transition to high rate production and recurring manufacturing product costs.Type: ApplicationFiled: May 20, 2015Publication date: January 14, 2016Applicant: Paideia LLCInventor: Elwood James Egerton

Patent number: 8110883Abstract: Electromagnetic radiation detecting and sensing systems using carbon nanotube fabrics and methods of making the same are provided. In certain embodiments of the invention, an electromagnetic radiation detector includes a substrate, a nanotube fabric disposed on the substrate, the nanotube fabric comprising a non-woven network of nanotubes, and first and second conductive terminals, each in electrical communication with the nanotube fabric, the first and second conductive terminals disposed in space relation to one another. Nanotube fabrics may be tuned to be sensitive to a predetermined range of electromagnetic radiation such that exposure to the electromagnetic radiation induces a change in impedance between the first and second conductive terminals. The detectors include microbolometers, themistors and resistive thermal sensors, each constructed with nanotube fabric. Nanotube fabric detector arrays may be formed for broad-range electromagnetic radiation detecting.Type: GrantFiled: March 12, 2008Date of Patent: February 7, 2012Assignee: Nantero Inc.Inventors: Jonathan W. Ward, Elwood James Egerton, Rahul Sen, Brent M. Segal

Patent number: 7062168Abstract: Multiple stage ranging circuitry for a measuring circuit includes a first ranging circuit that selectively amplifies an input signal by respective amounts according to the magnitude of the input signal thereto, and a second ranging circuit coupled to the output of the first ranging circuit selectively amplifies the output signal from the first ranging circuit by a respective amount according to the magnitude of that output signal to provide a measured output. The multiple stage ranging circuitry increases dynamic range and provides for high speed measurements over that dynamic range.Type: GrantFiled: March 19, 2002Date of Patent: June 13, 2006Assignee: DBM Optics, IncorporatedInventors: Michael Paul Atwell, Michael Paul Minneman, Elwood James Egerton

Patent number: 6846085Abstract: An miniature integrating sphere has a spherical volume with walls of a material for reflecting light, a light inlet and a light outlet. The light inlet is offset from a diameter axis of the spherical volume and the light inlet and light outlet are offset at non-perpendicular and non-parallel relation to each other. The light inlet is molded or milled to a shape conforming to the shape of the cone of light provided by a fiber optic device as an input to the integrating sphere. A number of miniature integrating spheres may be used respectively in plural channels of an optical measurement instrument.Type: GrantFiled: January 21, 2002Date of Patent: January 25, 2005Assignee: DBM Optics, IncorporatedInventors: Michael Paul Minneman, Douglas Fredrick Zahn, Elwood James Egerton

Patent number: 6784987Abstract: A range selection circuit (13), including a logarithmic amplifier (23) and output circuitry (25) associated therewith, is configured to directly drive linear ranging circuitry for measurement circuitry (12) in an optical power meter (10) to measure signals that vary over a wide range of, for example, from about −7 dB to about −45 dB. This allows the optical power meter to change ranges as fast as one (1) times the hardware settling time. The range selection circuitry is in parallel with the measurement circuitry, which allows ranging to happen in real time.Type: GrantFiled: January 21, 2002Date of Patent: August 31, 2004Assignee: DBM Optics, IncorporatedInventors: Michael Paul Minneman, Michael Paul Atwell, Elwood James Egerton
