Publication number: 20240189907Abstract: A method for printing electronic components is based on the hybridization of Fused Deposition Modeling (FDM) and laser sintering. The method involves printing a layer of composite copper-based thermoplastic filament on a base. Then the filament is subjected to a laser beam so as to selectively remove the polymer matrix in a restricted area after printing to leave only the conductive particles forming a highly conductive network and sintering the conductive particles with the laser energy to reveal the conductive copper. Then, alternately repeating the printing and sintering steps on the filaments one on top of the other until a complete component of arbitrary geometry, including both insulative and conductive structures, is formed layer-by-layer.Type: ApplicationFiled: December 11, 2023Publication date: June 13, 2024Applicants: VERSITECH LIMITED, ADVANCED BIOMEDICAL INSTRUMENTATION CENTRE LIMITEDInventors: Remi Rafael, Kwok Leung Chan

Patent number: 11438084Abstract: 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.Type: GrantFiled: March 13, 2020Date of Patent: September 6, 2022Assignee: Myriota Pty LtdInventors: Alexander James Grant, David Victor Lawrie Haley, Robert George McKilliam, William George Cowley, Ho Leung Chan
