  • Patent number: 12254094
    Abstract: A system and method for identifying authorized job step programs. The process identifies a plurality of job step programs. It then identifies authorized program facility (APF) authorized programs from the plurality of job step programs. An output table of APF authorized program is generated. This table is used to submit at least one batch job using the output table. A list identifying which parameters in a parameter string contain an address for each APF program in the output table is generated. This list is then provided for program testing.

  • Patent number: 12123633
    Abstract: The present invention aims to alleviate the risk of leakage of refrigerant from a refrigerant circuit and particularly at the utilization side of the refrigerant circuit without the need to provide a dedicated bypass for refrigerant leakage prevention. A refrigerant system is configured such that, when a refrigerant leakage detection sensor detects refrigerant leakage, a controller is configured to adjust a opening degree of a bypass expansion valve independently of a pressure and/or temperature value detected by a sensor. A method of controlling a refrigerant system is also provided.

  • Patent number: 11709936
    Abstract: Aspects of the invention include receiving, by a processor, source code for a software program written in a first programming language. The received source code is converted into abstracted source code that is in a generic format that is different than a format of the first programming language. The abstracted source code is compared to known source code patterns. Based on determining that at least a subset of the abstracted source code matches a pattern in the known source code patterns, sending an alert to the user indicating that the received source code matches the pattern.

  • Patent number: 10694981
    Abstract: A computer-implemented method of detecting physiological attributes of a wearer of a computerized wearable device having one or more sensors comprises (1) using the information from the one or more sensors to assess the physiology of the wearer; and (2) notifying the wearer of the wearer's physiology. In various embodiments, the method involves using the wearable device to determine the wearer's current posture, balance, alertness, and/or physical state and comparing the current posture, balance, alertness and/or physical state to at least one baseline measurement. For example, the system may measure a baseline posture to determine when the wearer's current posture deviates from the baseline posture, and notify the wearer so that the wearer may improve his or her posture. In other embodiments, the computerized wearable device may detect one or more of the wearer's physiological characteristics (e.g., oxygen levels, pulse rate, pupil size, etc.) and determine the wearer's alertness level.

  • Patent number: 10542915
    Abstract: A wearable device includes at least one sensor for obtaining a unique identifier from the wearer when the wearer and for transmitting the unique identifier to one or more computer processors for use in determining whether the wearer is a particular individual. The wearable device may also include a wireless communications device for transmitting a signal (e.g., to a remote computing device) that confirms the identity of the wearer as the particular individual. A remote computing device, or other device, or individual, may then, based at least in part on receiving the signal, grant wearer access to a computer program, computing system, and/or a particular physical space.

  • Patent number: 10448867
    Abstract: A system, according to various embodiments, includes eyewear (or any other suitable wearable device) that includes one or more sensors (e.g., one or more accelerometers, magnetometers, position sensors, gyroscopes, and/or other suitable sensors) that may be used to monitor the gait of an individual (e.g., by monitoring the movement of the user's head, or other portions of the user's body, as the user ambulates). The system may further include one or more suitable computing devices for analyzing the individual's gait. This information may then be used, for example, to: (1) identify one or more medical conditions associated with the individual; (2) assess the fit of a prosthetic device worn by the individual, and/or (3) assess an individual's recovery from a particular injury or medical procedure.
