Abstract: A vehicle detection system warns snowmobilers of other approaching vehicles with potential risk of collision. To better prevent accidents, the system calculates collision risks and warns the rider based on level of risk. When riding in groups, a member can press a stop request button to ask the group to slow down. When a member exits the group, everyone in the group will receive a message, alerts or indication with the update. The vehicle detection system utilizes Bluetooth® low energy (BLE), LoRaWAN® technologies and/or global positioning system technologies and is designed to detect other devices in the region and use acquired information to calculate proximity and risk of collision.

Abstract: Disclosed herein are processes for producing metal-organic framework (MOF) materials (e.g., ZIF-67), as well as MOF-coated light emitted diodes (LEDs). The process for producing ZIF-67 nanoparticles includes (a) mixing a solution of cobalt(II) hexahydrate and a solution of 2-methylimiazole to give a first mixture solution; and (b) let the first mixture solution stand for a sufficient period of time to allow the growth of the ZIF-67 nanoparticles. The process for producing a ZIF-67-coated light emitted diode (LED) includes (i) dispersing the ZIF-67 nanoparticles in a poly (methyl methacrylate) (PMMA) solution to form a ZIF-67@PMMA slurry; and (ii) applying the ZIF-67@PMMA slurry onto the surface of an LED in a dropwise manner to give the ZIF-67@PMMA-coated LED.

Abstract: The present disclosure provides systems and methods which increase the throughput of a TCP-based communication between a first network node and a second network node. First, the first network node sent a first plurality of TCP segments to the second network node. Second, when the second network node receives a second plurality of TCP segments, which is all or part of the first plurality of the TCP segments, the second network node responds by sending one or more TCP acknowledgements to the first network node with the last sequence number of a last segment among all TCP segment within the second plurality of TCP segments. The present disclosure are able to increase the throughput of a TCP connection while decreasing its reliability.

Abstract: The present disclosure relates to manufacturing techniques for manufacturing multiple semiconductor package assemblies on a lead frame, as well as a semiconductor package assembly manufactured using this method. The method reduces the distances or intermediate spacings between singulated semiconductor packages on a lead frame to a width equal to the width of a cutting tool which width is significantly smaller than the distance required in any known modelling encapsulation technique. Therefore, the method according to the disclosure allows to position more semiconductor packages on a lead frame on one process step. Accordingly, as the number of semiconductor packages per lead frame surface is increased, more semiconductor packages can be manufactured and singulated in one process step, which reduces costs and processing time.

Abstract: An electronic package and method for manufacturing is provided. The package includes an electronic component having a terminal, a solidified molding compound encapsulating the electronic component, a lead including an inner and a mounting portion. The molding compound includes a first recess at or near a perimeter of a bottom surface of the mounting portion, exposing a portion of a bottom surface of the inner portion arranged near the mounting portion, and/or a second recess at the perimeter of the bottom surface of the mounting portion, the second recess exposing a portion of a side surface of the mounting portion extending between the top and the bottom surface of the mounting portion. The package provides more exposed lead space for a larger solder covering area using the first and/or second recess. Thus, solder strain accumulation is reduced or mitigated, and reliability of the electronic package can be enhanced.

Abstract: A multiple access slotted wireless communication system comprising a plurality of terminals and a multi-access receiver is described. The multi-access receiver can decode multiple transmissions in each slot of a frame from terminals in its field of view. Each terminal has an active state for transmitting and an inactive state. After receiving acknowledgement of a successful transmission by the terminal, the terminal enters the inactive state for at least a transmission delay time. This may be the remaining time that the terminal is in the field of view of the multi-access receiver. This may be achieved by the terminal using a probability of transmission to determine whether or not to transmit in the next frame. The terminal may also be configured to select the slot in a frame, and this may be based upon information such as which slots were acknowledged. The receiver may use compression to transmit acknowledgement messages.
