Abstract: The present invention provides a blockchain-based method and system for processing a traffic violation event. The method includes: obtaining traffic violation reporting information provided by a first vehicle node stored in a blockchain; obtaining an associated evidence data identifier in the traffic violation reporting information; obtaining, according to the evidence data identifier, evidence data provided by a second vehicle node stored in the blockchain; and determining, according to the traffic violation reporting information and the associated evidence data, whether the traffic violation reporting information is valid. In the present invention, each vehicle node in the blockchain automatically collects data of a traffic violation event, so that credible traffic violation determining is completed based on an intelligent contract, and credibility and tamper resistance of traffic violation determining is improved based on recording information of a plurality of associated blockchain nodes.

Abstract: Various embodiments of the present application are directed towards a control gate layout to improve an etch process window for word lines. In some embodiments, an integrated chip comprises a memory array, an erase gate, a word line, and a control gate. The memory array comprises a plurality of cells in a plurality of rows and a plurality of columns. The erase gate and the word line are elongated in parallel along a row of the memory array. The control gate is elongated along the row and is between and borders the erase gate and the word line. Further, the control gate has a pad region protruding towards the erase gate and the word line. Because the pad region protrudes towards the erase gate and the word line, a width of the pad region is spread between word-line and erase-gate sides of the control gate.

Abstract: A cervical assist pillow, comprising, a lower back support portion having a wedge therein to accept a user's upper back and shoulders, an upper neck support portion adjacent the lower back support portion, the upper neck support portion having an extended height to support the users neck proximate a user's head and having a height to elevate the user's neck at a cervicomental angle between approximately 100 and 120 degree, a head support portion adjacent the upper neck support portion and having a concavity to accept the back of the user's head and a waist belt coupled to the lower back support portion at a first end and detachably couple-able to a user's midsection to prevent slippage from under the user's head and neck.

Abstract: An adjustable cervical collar, comprising, a curved top board having a width of approximately a size of a human chin, the curved top board having an arcuate inner edge capable of fitment around the front of a throat, the curved top board having a curved outer region distal to the throat, two upper columns couple-able to a lower portion of the curved top board, two lower columns slidably couple-able to the two upper columns and a curved bottom board detachably couple-able to the two lower columns.

Abstract: Highly secured transactions for mobile or Internet-of-Things (IoT) devices can be conducted using a one-time seed technology (OTST). For example, registration of a user and authentication of a user device is based on a one-time seed (OTS) which is generated by an authentication server and sent to the user device. The user device employs the OTS to generate a one-time password (OTP). After registration and authentication, the OTS is deleted. As such, the OTS and OTP is used only one time. No seed is stored on the user device. As for securing the transactions, it may be signed by a one-time hash (OTH) or a one-time signing key (OTSK). Like the OTS, the OTH or OTSK is deleted from the user device after the transaction. Since the user device does not contain a seed, OTH or OTSK, there is no risk of the user device being hacked by unwanted third parties.
