Abstract: A wafer scale ultrasonic sensor assembly includes a wafer substrate, an ultrasonic element, first and second protective layers, conductive wires, a transmitting material, an ASIC, a conductive bump, and a soldering portion. The wafer substrate includes a via. The ultrasonic element is exposed to the via. The conductive wires are on the first protective layer and connected to the ultrasonic element. The second protective layer covers the conductive wires, and the second protective layer has an opening corresponding to the ultrasonic element. The transmitting material contacts the ultrasonic element. The ASIC is connected to the wafer substrate, so that the via forms a space between the ASIC and the ultrasonic element. The conductive pillar is in a via defined through the ASIC, the wafer substrate, and the first protective layer, and the conducive pillar is respectively connected to the conductive wires and the soldering portion.

Abstract: The present disclosure discloses a lamp holder, a battery assembly and a supplementary lighting lamp. The lamp holder includes a housing and a rotation assembly rotating relative to the housing, wherein the rotation assembly includes a cover body, a resisting member and an adjusting member moving relative to the cover body, and the housing includes a fastener formed on a first end thereof. The adjusting member moves on the cover body so that the resisting member is resisted against the fastener, thus the rotation assembly is clamped with the housing or separated from the housing. The present disclosure has the advantages of convenient disassembly and good waterproof performance.

Abstract: A flexible device includes two opposite sides and a flexible functional element. Each side includes a movable element having a top portion. The flexible functional element includes a flexible functional screen and a support plate supporting the flexible functional screen. The support plate includes a plate body and fixing sheets extending from the plate body. The plate body separably abuts against the top portions of the movable elements, and the fixing sheets fix to the movable elements.

Abstract: A UV light and sterilization system. The UV light includes: a base, a reflex lamp housing and several UV modules; the reflex lamp housing is provided on the base, the periphery of the reflex lamp housing is provided with several containing grooves, and the inner wall of each of the containing grooves is provided as a reflective panel; several the UV modules are provided on the base and connect to the base electrically, and each of the UV modules is contained in a the containing groove.

Abstract: The present invention relates to an electronic atomizing device and a liquid injecting structure thereof. The liquid injecting structure includes an outer tube and a liquid injection assembly in the outer tube. The outer tube defines an inlet port, the liquid injection assembly includes a switch assembly rotatable between an injecting position and a working position relative to the outer tube; the switch assembly includes a liquid injection tube defining an injecting port. When the switch assembly is in the injecting position, the injecting port is fluidly communicated with the inlet port, such that liquid can be injected into a liquid storage cavity; when the switch assembly is in the working position, the injecting port is isolated from the inlet port. The rotation operation is child-resistant; when the switch assembly is in the working position, the liquid injecting structure is shielded by a battery and cannot be opened accidentally.

Abstract: A method to protect code against altering includes reading immutable boot code from a ROM. A code image is loaded from an external memory and a hash is calculated by a core unit. The hash is initially authenticated using the boot code for decrypting the hash of the external memory. A salted hash for each equivalent of a cache line of the code image is concurrently calculated by a cache protection block and the salted hash for each cache line in an internal hash table is stored. If the authentication succeeds, a part of the code image is loaded into a secure cache of the embedded micro-processor.

Abstract: A payment method by a processing server to process payment that is independently performed between a user equipment and a payment channel server is provided. The method includes: generating, by the processing server, a payment order bound to a merchant order generated by a merchant device by determining a corresponding item ID, of a service and/or a product for purchase, that is registered with the payment channel server, the merchant order corresponding to the service and/or the product provided by the merchant device; obtaining, by the processing server, a payment voucher corresponding to the payment order; matching, by the processing server, based on the payment voucher, the merchant order bound to the payment order; and transmitting, by the processing server to the merchant device, based on the matched merchant order, a service/product providing notification for providing the service and/or the product to the user equipment.
