  • Publication number: 20190303877
    Abstract: Systems and methods for analyzing pipelined data are disclosed. In some examples, a server receives a transaction description requesting candidates for a given transaction. The server accesses first records representing parties that fully completed the given transaction and second records representing parties that were in a pipeline for completing the given transaction but did not fully complete the given transaction. The first records and the second records are stored at a data repository. The server generates a model for predicting whether an identified record represents a party likely to complete the given transaction. The model is generated based on at least the first records and the second records. The server orders a list of third records representing parties likely to complete the given transaction. The server provides an output representing the third records.

  • Patent number: 10424378
    Abstract: In one example in accordance with the present disclosure a control circuit is described. The control circuit includes a source following component to receive an input voltage and output a switching voltage. The circuit also includes an input leg of a current mirror coupled to the source following component. The input leg of the current mirror replicates the switching voltage to an output leg of the current mirror of a memristive bit cell. The circuit also includes a number of current control components. At least one of the current control components enforces a constant current through the source following component and other current control components maintain the input leg of the current mirror and the output leg of the current mirror at the same current.

  • Publication number: 20190287070
    Abstract: Systems and methods for query expansion are disclosed. In some examples, a server receives, from a client device, a search query for employment candidates, the search query comprising a first set of parameters. The server determines a second set of parameters related to the first set of parameters in response to identifying a second parameter for the second set of parameters that corresponds with a first parameter from the first set of parameters, the professional records being stored in a professional data repository. The server generates, from the professional data repository, a first set of search results based on the first set of parameters and the second set of parameters. The server provides, to the client device, an output representing the first set of search results.

  • Patent number: 10418103
    Abstract: According to examples, an apparatus may include a ternary content addressable memory (TCAM) including a plurality of TCAM bit cells connected in a row along a match line. Each of the TCAM bit cells may store a bit of a TCAM word and the TCAM bit cells may drive a digital signal over the match line in response to a search word matching the TCAM word. The apparatus may include a resistive random-access memory (RRAM) comprising a row of RRAM bit cells connected to the TCAM via the match line. Each of the RRAM bit cells may store a bit of a RRAM word. The RRAM bit cells may output the RRAM word in response to the TCAM bit cells driving the digital signal over the match line.

  • Publication number: 20190235458
    Abstract: An example finite state machine may include a content-addressable memory. The content-addressable memory may include blocks that respectively store input-terms of the finite state machine. The finite state machine may be configured to, for each received input: select a subset of the blocks of the content addressable memory to enable for searching, the subset being selected based on a current state of the finite state machine, and determine a next state of the finite state machine by searching the currently enabled subset of blocks of the content addressable memory based on the input.

  • Publication number: 20190237137
    Abstract: In one example in accordance with the present disclosure a device is described. The device includes a cross-bar array of memristive elements. Each memristive element has a conductance value. The device also includes a column of offset elements. An offset element is coupled to a row of memristive elements and has a conductance value. The device also includes a number of accumulation elements. An accumulation element is coupled to a column of memristive elements. The accumulation element collects an intermediate output from the column and subtracts from the intermediate output an output from the column of offset elements.

  • Patent number: 10332592
    Abstract: Examples herein relate to hardware accelerators for calculating node values of neural networks. An example hardware accelerator may include a crossbar array programmed to calculate node values of a neural network and a current comparator to compare an output current from the crossbar array to a threshold current according to an update rule to generate new node values. The crossbar array has a plurality of row lines, a plurality of column lines, and a memory cell coupled between each unique combination of one row line and one column line, where the memory cells are programmed according to a weight matrix. The plurality of row lines are to receive an input vector of node values, and the plurality of column lines are to deliver an output current to be compared with the threshold current.

  • Publication number: 20190188273
    Abstract: Systems and methods for query term weighting are disclosed. A server receives a search query for employment candidates, the search query comprising a set of parameters, each parameter having a weight. The server generates, from a data repository storing records associated with professionals, a first set of search results based on the set of parameters and the weights of the parameters in the set. The server transmits the first set of search results. The server receives a response to search result(s) from the first set of search results, the search result(s) being associated with a set of factors, the response indicating a level of interest in the search result(s). The server adjusts the parameters in the set of parameters or adjusts the weights of the parameters based on the response to the search result(s). The server provides an output based on the adjusted parameters or the adjusted weights.

  • Patent number: 8132277
    Abstract: An emergency response treatment bed system. The emergency response beds may include a frame having a pair of opposing tubular stainless steel side supports and a pair of opposing tubular stainless steel end supports. The side supports and end supports are affixed each to the other by corner fixtures. A plurality of collapsible support legs are affixed to the frame. The support legs have an upper end and a lower end, and are adapted to support the frame above a selected substrate. A support deck is coupled to the frame. The support deck is adapted to support a patient body, and is provided with a liquid impervious, molded thermoplastic contaminant resistant cleanable surface. The support deck also has, above at least some of the support legs, a cutout portion defined by edgewalls, to provide access through the support deck to the support legs, so that multiple beds may be stacked one above the other, using support inserts between vertically adjacent support legs.
