  • Publication number: 20240088591
    Abstract: A conductive terminal assembly includes at least three layers of conductive terminals. Each layer of conductive terminals has a terminal body, one or more elastic arms extending from the terminal body, and a contact end at an end of each elastic arm distal from the terminal body in a first direction. The terminal bodies of the at least three layers of conductive terminals are overlapped with each other in a second direction perpendicular to the first direction. The contact ends of the at least three layers of conductive terminals are at least partially staggered and arranged in a third direction perpendicular to the first direction and the second direction. The contact ends are capable of electrically contacting a mating component.

  • Publication number: 20240088592
    Abstract: An electrical connector includes a housing defining a slot in which a mating component can be at least partially inserted, a conductive terminal installed in the housing and having a contact end capable of electrically contacting the mating component, and a supporting member elastically supporting the contact end. The supporting member has a cantilever beam and a supporting arm extending from the cantilever beam. The cantilever beam at least partially abuts a first surface of the contact end facing an inner wall of the housing and applies an elastic force to the contact end. The supporting arm is positioned at least partially between the cantilever beam and the inner wall. The supporting arm elastically supports the cantilever beam and the contact end when pressed against the inner wall.

  • Patent number: 7961882
    Abstract: Methods and apparatus are provided for using explicit initialization vectors in both encryption and decryption processing. In one example, a sender generates an initialization vector, identifies cryptographic keys, encrypts data using the initialization vectors and the cryptographic keys, and transmits the encrypted data in a packet along with the initialization vector. A receiver identifies cryptographic keys, extracts the initialization vector from the received packet, and decrypts the encrypted data using the cryptographic keys and the initialization vector extracted from the received packet.

  • Patent number: 7757063
    Abstract: There are disclosed systems and computer program products for dynamically resizing memory pools used by database management systems. In one aspect, if a decrease in allocation to the memory pool is required, at least one page grouping that may be freed from the memory pool is identified as a candidate based on its position in a list of page groupings. If the page grouping contains any used memory blocks, the used memory blocks may be copied from a candidate page grouping to another page grouping in the list in order to free the candidate page grouping. Once the candidate page grouping is free of used memory blocks, the candidate page grouping may be freed from the memory pool. As an example, this system or computer program product may be used for dynamically resizing locklists or lock memory.
