Patent number: 11938310Abstract: A gas removal apparatus and a method for removing gas bubbles from at least a part of a medical device disposed in an interior chamber of a gas removal apparatus. The gas removal apparatus includes an interior chamber, a filling surface, a first opening arranged at an end of the filling surface and that provides a first path into the interior chamber, and a second opening that provides a second path into the interior chamber. When the apparatus is arranged in a liquid receiving position, at least a portion of the at least the part of the medical device is disposed above an uppermost surface of liquid in the interior chamber, and when the apparatus is arranged in another position different from the liquid receiving position, the entirety of the at least the part of the medical device is disposed below an uppermost surface of liquid in the interior chamber.Type: GrantFiled: January 30, 2020Date of Patent: March 26, 2024Assignee: KARDIUM INC.Inventors: Lok Tin Lam, Saar Moisa, Ashkan Sardari

Patent number: 11911091Abstract: In at least a medical system including a structure, a plurality of transducers located on the structure, a shaft member configured to percutaneously deliver the structure to a location within a patient, a plurality of conductors at least partially within the shaft member and coupled to the transducers, and a controller operatively coupled to the transducers via the conductors, the controller may cause first electrical power to be delivered to one or more of the transducers for a first period of time, where second electrical power less than the first electrical power, if delivered for a second period of time longer than the first period time would result in a steady-state temperature of a portion of the shaft member that would be just below a safe temperature limit for at least the portion of the shaft member.Type: GrantFiled: October 23, 2019Date of Patent: February 27, 2024Assignee: KARDIUM INC.Inventors: Daniel Robert Weinkam, Shane Fredrick Miller-Tait, Lok Tin Lam

Publication number: 20170164953Abstract: A hammer drill attachment is provided for attachment to a bi-directional surgical drill. The attachment comprises a lengthwise adapter to engage a chuck of the surgical drill, a transmission mechanism, and a quick-release mechanism. The transmission mechanism comprises a pair of toothed plates, the teeth of a proximal plate configured to permit engagement with the teeth of a distal plate. When the proximal plate rotates in a first direction, the proximal plate transmits a rotational motion to the distal plate. When the proximal plate rotates in a second direction, the proximal plate transmits an axial percussive force to the distal plate. The quick-release mechanism comprises a socket to receive a collet, a socket seater, and a latching arm to move the socket seater with respect to the socket, thereby seating or unseating the collet in the socket.Type: ApplicationFiled: February 23, 2017Publication date: June 15, 2017Applicant: BRITISH COLUMBIA CANCER AGENCY BRANCHInventors: Lok Tin LAM, Scott Elton YOUNG, Derek THONG

Patent number: 7707217Abstract: A method performs a lookup on a search key word, employing a trie database including multiple trie blocks that include pointers to other trie blocks. Each trie is accessible by means of a segment of the search key. A selected section of the search key word is applied to a content addressable memory. In the event of an absence of a match of the selected section with an entry in the content addressable memory, a trie search is performed on the whole search key word. In the event of a match of the selected section with an entry in the content addressable memory, a partial trie search is performed, commencing with a first segment of the search key word after the selected section that has been matched in the content addressable memory.Type: GrantFiled: January 24, 2005Date of Patent: April 27, 2010Assignee: 3Com CorporationInventors: Gareth Edward Allwright, Eugene O'Neill, Tin Lam, Kam Choi, Francisco Valentin Aquino

Publication number: 20060167843Abstract: A search engine operable to search on a search key word of a given length comprises a trie database which supports a trie search on keys of the given length and a content addressable memory organized to receive a most significant section of the search key word. The search engine performs a full trie search on the whole of said search key word in the event of no match of a most significant section within the content addressable memory. In the event of a match within the content addressable memory the search engine performs a partial trie search commencing with a trie block pertaining to a first segment of the search key word after the most significant section which has already been matched.Type: ApplicationFiled: January 24, 2005Publication date: July 27, 2006Inventors: Gareth Allwright, Eugene O'Neill, Tin Lam, Kam Choi, Francisco Valentin Aquino

Patent number: 6751700Abstract: A data processor and storage system which comprises a data processor, a cache memory and a main memory is arranged so that the addressing of the main memory produces a multiplicity of spaced aliases, the multiplicity being greater than the set-associativity of the cache memory. The cache memory may be a multiple way set associative cache memory with the system including a round robin allocator for controlling the storing of successive data items in the different ways of the set associative cache. The cache may also be a direct mapped cache having single way set-associativity so that the round robin allocator is not required. The system may also include a direct memory access (DMA) device for copying data items into the memory. The memory may be a buffer memory which is divided into a plurality of packet buffers.Type: GrantFiled: April 2, 2001Date of Patent: June 15, 2004Assignee: 3Com CorporationInventors: Bryan J Donoghue, Lee C Harrison, Edward Turner, Tin Lam, Victoria A Griffiths
