Abstract: A temperature-activatable temperature indicator that includes a substrate and an indicator material supported by the substrate. The indicator material includes a mixture of a side-chain crystalline polymer and conductive particles and provides an electrical indication of exposure to increased temperature.

Abstract: A device for processing fully homogeneous encrypted data comprises a command input with pipeline stages and a register file coupled to the command input via a non-pipelined stage and an ultimate pipelined stage. Further, the device includes various multiplexers to allow for usage of a multiplier for different command functions. Moreover, the device includes an adder element with a first input coupled to multiplexer outputs, a select line coupled to a penultimate pipeline stage of the command input, and an output coupled to the register file. A command on the command line passes through the pipeline stages as select inputs to the multiplexers to control the function of the multiplexers at that time.

Abstract: A method for reducing calculation time for processing fully homomorphic encrypted (FHE) data comprises pre-calculating a second half of a key-switching key, storing the second half of the key-switching key in memory, and receiving FHE data. After the FHE data is received, the method determines a first half of the key-switching key by randomly generating a first half of the key-switching key. The key-switching key is then constructed by retrieving the second half of the key-switching key from the memory and appending the second half of the key-switching key to the first half of the key-switching key. After the key has been constructed, a key-switching operation is performed on the FHE data using the key-switching key.

Abstract: A device for executing programs and processing data that have been homomorphically encrypted is presented. The device includes an interface to a host system board, a mass memory, and a high-speed bus interconnect coupled to the mass memory and the interface. Further, a dedicated fully homomorphic encryption accelerator is coupled to the mass memory, the high-speed bus interconnect, and the interface. The interface both receives input data to be stored in the mass memory and sends output data from the mass memory to the processing board. The dedicated fully homomorphic encryption accelerator converts the input data to output data by performing operations on the input data.

Abstract: A method for conflict-free memory accesses comprises storing data in a memory. The memory can be accessed by row or column, and the data is arranged in a scrambled ordering. Further, the process includes defining a bank as a specified row exclusive or-ed with a specific column. When addressing a row, mapping a bank i to an index i xor the row. On the other hand, when addressing a column, mapping a bank i to an index i xor the row.

Abstract: The present disclosure is directed to a method of making a phosphite ester. The method comprises reacting a hydroxyl-substituted compound comprising a hydroxyl-substituted alkyl compound, a hydroxyl-substituted aryl compound, or a mixture thereof with a phosphorus halide to make a product mixture comprising a hydrogen halide and a reaction product comprising the phosphite ester and a phosphohalodite and removing the hydrogen halide from the product mixture.

Abstract: Disclosed herein are delayed reaction threshold temperature indicators and methods of making and activating the same, the delayed reaction threshold temperature indicators including a first substrate, first and second layers, and a housing secured to the substrate. The first layer includes a first reactant and an optional meltable polymer, and the second layer includes a meltable polymer and a second reactant. The meltable polymer is configured to keep the first and second reactants from interacting with each other. When exposed to temperatures at and/or above a desired threshold for a period of time, the meltable polymer melts and allows the first and second reactants to come into contact with each other, thereby producing a visual change in appearance.

Abstract: A freeze indicator can include an indicator dispersion having an aqueous liquid medium and organic material indicator particles dispersed in the aqueous liquid medium. The indicator dispersion can have an initial appearance before freezing and an irreversibly different appearance after freezing and can exhibit a freeze-onset temperature of about ?1.9° C. or higher. Some factors helpful to providing a relatively high freeze onset temperature are employment of a proteinaceous ice-nucleating agent, control of pH, use of a protein stabilizer and control of the ratio of protein stabilizer to ice-nucleating agent.
