  • Patent number: 11985784
    Abstract: A server information handling system is secured by a bezel that couples to an access location, such as an air vent at a front or rear face of a housing. The bezel includes a security structure having a lock and configured to couple directly at the front face or with a bezel extension at the rear face so that the server information handling system can use the same bezel with both a front face or rear face rack mount. The bezel has a lock integrated with the security structure, an air filter that fits over the security structure to filter air flowing into the housing, and a filter brace that captures the air filter by coupling to the security structure over the air filter. The filter brace attaches and detaches at the security structure when the security structure locks a server information handling system housing so that the air filter can be changed while the housing remains secure.

  • Patent number: 11966628
    Abstract: A memory device, includes a memory array for storing a plurality of vector data each of which has an MSB vector and a LSB vector. The memory array includes a plurality of memory units each of which has a first bit and a second bit. The first bit is used to store the MSB vector of each vector data, the second bit is used to store the LSB vector of each vector data. A bit line corresponding to each vector data executes one time of bit-line-setup, and reads the MSB vector and the LSB vector of each vector data according to the bit line. The threshold voltage distribution of each memory unit is divided into N states, where N is a positive integer and N is less than 2 to the power of 2, and the effective bit number stored by each memory unit is less than 2.

  • Patent number: 11955338
    Abstract: A method includes providing a substrate having a surface such that a first hard mask layer is formed over the surface and a second hard mask layer is formed over the first hard mask layer, forming a first pattern in the second hard mask layer, where the first pattern includes a first mandrel oriented lengthwise in a first direction and a second mandrel oriented lengthwise in a second direction different from the first direction, and where the first mandrel has a top surface, a first sidewall, and a second sidewall opposite to the first sidewall, and depositing a material towards the first mandrel and the second mandrel such that a layer of the material is formed on the top surface and the first sidewall but not the second sidewall of the first mandrel.

  • Publication number: 20230343425
    Abstract: Disclosed are methods and the non-transitory computer storage media of extracting linguistic patterns and summarizing a pathology report thereof. The present disclosure provides a method of extracting key linguistic patterns from a pathology report. The method comprises: determining a confidence degree and a support degree between a linguistic term and a next linguistic term based on co-occurrences of the linguistic term and the next linguistic term; generating a set of candidate linguistic terms; generating a first set of linguistic patterns through performing random walks on the set of candidate linguistic terms; and determining the key linguistic patterns through removing redundant linguistic patterns from the first set of linguistic patterns.

  • Patent number: 11052513
    Abstract: A pneumatic-fixation connecting having a body, a movable part, a plurality of spheres, a plurality of elastic units, and a plurality of stop units is disclosed, wherein each of the elastic units is disposed between the body and the movable part via each of the stop units, respectively. When an external force is applied on the movable part, the distance between the movable part and the body is reduced and the sphere does not block the connecting pin in the extension tube inside the body. When the external force disappears, the distance between the movable part and the body increases such that the sphere affixes the connecting pin and the body. The stop unit can be used, not only to adjust the length and elastic force of the elastic unit so as to extend the life cycle of the elastic unit, but also to help in changing the elastic unit which in turn enhances the efficiency of the replacement work.
