Abstract: J'ai confectionnée la poubelle réfrigérer au mois de Février 2017 a partir d'un mini réfrigérateur et d'une poubelle de 20 litres. Cette invention a pris naissance suite à un conflit entre ma conjointe et moi, qui voulais composter à l'année même durant nos été chaude. La poubelle fournie par la municipalité n'était pas adaptée pour prévenir la formation de vers blanc ainsi que l'élimination des odeurs intense et désagréable. Depuis l'utilisation de la poubelle réfrigérée les vers blanc sont complètement disparus car le sac de compost est congelé et dégage un parfum de citron qui éloigne les parasites. J'ai conçu cette poubelle pour accueillir des sacs compostables, acheter chez les marchands IGA avec la dimension idéal et un coût aussi peu que 30 sous chaque. Notre quantité de déchet résidentielle à diminués de 60% pour le même pourcentage d'augmentation de compost Maintenant nous produisions 2,5 kilos d'ordures par mois et environ 18,14 kilos de matière compostable mensuels.

Abstract: Leakage-aware activation control of a delayed keeper circuit for a dynamic read operation in a memory bit cell is disclosed. In one aspect, a leakage-aware activation control circuit is provided for a dynamic read circuit configured to perform read operations on a memory bit cell. To prevent or mitigate contention between the delayed keeper circuit and a read port circuit in the dynamic read circuit pulling a dynamic node to opposite voltage levels when a read operation is initiated, the leakage-aware activation control circuit is configured to adaptively control activation timing of the delayed keeper circuit based on a comparison of N-type Field-Effect Transistor (NFET) leakage current to P-type FET (PFET) leakage current. In this manner, the leakage-aware activation control circuit can adaptively adjust the activation timing of the delayed keeper circuit based on the actual relative strengths of NFETs and PFETs.

Filed: 2017-02-24
Abstract: Techniques for transmitting an optical signal through optical fiber with an improved stimulated Brillouin scattering (SBS) suppression and an improved transmitters signal to noise ratio (SNR) include externally modulating a light beam emitted from a light source with a high frequency signal. The light beam is also modulated externally with an RF information-carrying signal. The high frequency signal is at least twice a highest frequency of the RF signal. The high frequency signal modulating the light source can be split, providing a portion of the split signal to a phase and gain control circuit for adjusting a phase/gain. The output of phase and gain control circuit can be applied to the external modulator to eliminate intensity modulation for SBS suppression improvement. The optical transmitters SNR is further improved by cancelling a beat between SBS suppression modulation tone and out of band distortion spectrum of information bearing RF signal.

Abstract: Disclosed systems and methods pertain to finfet based integrated circuits designed with logic cell architectures which support multiple diffusion regions for n-type (503, 504) and p-type (501, 502) diffusions. Different diffusion regions of each logic cell can have different widths or fin counts. Abutting two logic cells is enabled based on like fin counts for corresponding p-diffusion regions and n-diffusion regions of the two logic cells. Diffusion fills are used at common edges (570) between the two logic cells for extending lengths of diffusion, based on the like fin counts. The logic cell architectures support via redundancy and the ability to selectively control threshold voltages of different logic cells with implant tailoring. Half-row height cells can be interleaved with standard full-row height cells.

IPC: A01P7/04
Filed: 2017-11-13
Abstract: Modulation of inward potassium ion conductance with structurally diverse small-molecules in the arthropod salivary gland induces arthropod salivary gland failure that results in a reduction or elimination in the ability of the arthropod to feed. Administering Kir channel inhibitors reduces food intake, increases feeding time, reduces salivary gland secretion, induces mortality, and reduces transmission of vector-borne pathogens. Kir channel inhibitors induce these adverse effects in ticks, mosquitoes, horn flies, and aphids.
