Patent number: 11954095Abstract: A set of transaction handling computing elements comprise a network core that receive and process transaction requests into an append-only immutable chain of data blocks, wherein a data block is a collection of transactions, and wherein an Unspent Transaction Output (UTXO) data structure supporting the immutable chain of data blocks is an output from a finalized transaction. Typically, the UTXO data structure consists essentially of an address and a value. In this approach, at least one UTXO data structure is configured to include information either in addition to or in lieu of the address and value, thereby defining a Transaction Output (TXO). A TXO may have a variety of types, and one type includes an attribute that encodes data. In response to receipt of a request to process a transaction, the set of transaction handling computing elements are executed to process the transaction into a block using at least the information in the TXO.Type: GrantFiled: January 3, 2023Date of Patent: April 9, 2024Assignee: Akamai Technologies, Inc.Inventors: William R.

Patent number: 9805869Abstract: A solid state electrical energy state storage device includes multiple dielectric layers or an integral heterogeneous dielectric layer. Layers or portions of the heterogeneous layer have permittivity augmented by exposing the dielectric material to electric/magnetic fields during formation of the dielectric before complete solidification. Such exposure results in radicals and/or an ordered matrix. A dielectric for the device may contain a new xylene based polymer formed under atmospheric conditions via reaction with monatomic oxygen and provided an augmented permittivity through exposure of the polymer to a magnetic field and/or an electric field during condensation and solidification on a substrate.Type: GrantFiled: December 31, 2012Date of Patent: October 31, 2017Assignee: Carver Scientific, Inc.Inventors: David R.

Patent number: 5969812Abstract: A spectrophotometer measures optical absorption of light by a sample received in a sample cell. An array of optical elements disperses the light over a spectral pattern, and a fiber optic beam splitter splits light at a selected spectral band into a reference component and a test component. Detectors measure the intensity of the reference component and the test component after the test component passes through the sample. The fiber optic beam splitter includes a plurality of strands arranged with first ends terminating in a common circular area. Opposite ends of peripheral strands are collected into a first set that transmits the test component while the remaining strands for a second set that transmits the reference component. Preferably, there is a single, central, large strand surrounded by smaller strands. Two emitters are provided for light of two different types, such as visible and UV. The optical array forms a collimated beam having an inner core of one type of light and an outer shell of the other.Type: GrantFiled: October 18, 1995Date of Patent: October 19, 1999Inventor: David R.

Patent number: 5699156Abstract: A spectrophotometer employs an array of optical elements to focus light from at least one, but preferably two light sources onto a fiber optic beam splitter that provides a pickup for a selected bandwidth of wavelengths of light in the spectral pattern. The spectral pattern can include wavelengths in the visible, near infrared and ultraviolet spectrum. To create the spectral pattern, two reflecting prisms having spherical surfaces are used, and the optical elements are arranged so that the two spectral bands from each prism are longitudinally aligned to create the spectral pattern. The prisms are on a motor driven pivot mount so that the spectral pattern may be swept across the pickup. The optical elements and the pickup are sized so that the selected bandwidth is less than twenty nanometers over the spectral pattern. The pickup is formed by a single row of the ends of fiber optic strands which are then collimated into two bundles to transmit a test component and a reference component of light.Type: GrantFiled: November 23, 1994Date of Patent: December 16, 1997Inventor: David R.

Patent number: 5694215Abstract: A sample cell assembly employs optics for focusing light though a sample cell, such as one used in electrophoresis. The optical array includes a first cylindrical lens having a central longitudinal axis in a common plane with the longitudinal axis of the sample cell. A second cylindrical lens has its central longitudinal axis oriented transversely to this common plane on another side of the sample cell from the first cylindrical lens. Preferably, a fiber optic beam splitter has a plurality of strands terminating in parallel second ends in the common plane so as to pass light at different longitudinally spaced locations through the sample cell cavity. Here, a plurality of second lenses receive the different light components to focus them respectively on different photodetectors each to create a sample data signal. Where a plurality of sample data signals are generated, processing electronics superimpose them to obtain an augmented signal of aggregate data.Type: GrantFiled: March 4, 1996Date of Patent: December 2, 1997Inventor: David R.
