  • Publication number: 20210016097
    Abstract: Methods and systems for dynamically modifying pacing timing and backup pacing delivery in cardiac stimulation devices include applying pacing impulses, measuring corresponding responses, and, based on such responses, automatically modifying timing or operational settings of the stimulation device to improve pacing functionality. Among other things, the approaches described herein reduce unnecessary backup pacing impulses in HIS bundle pacing applications, facilitate fusion in bundle branch block applications, and automatically enable or disable backup pacing in response to achieving QRS complex correction.

  • Patent number: 8700903
    Abstract: The process of acquiring SSL certificates for enterprise SSL customers is improved by reducing the number of steps used to acquire the SSL certificate and streamlining the process. An on-line CSR generator on the certificate enrollment form is used to submit the customer information (i.e. Common Name, Organizational Unit, Organization, City/Locality, State/Province, and Country Code) and generate the CSR. By making the CSR generation part of the enrollment process, the administrator can use the same enrollment form to submit the customer information along with the contact information pertinent to the enterprise.

  • Patent number: 5819030
    Abstract: A technique for configuring a server computer using an optimizer program to achieve optimal performance of the server based on the server types supported by the server. Configuration may involve both calculating server configuration parameters and deciding where to place various files used by the server. In order to decide where to place files, the hardware and software characteristics of the server disk drives are analyzed, and a performance table is generated. The disk drive performance data is then input into a series of algorithms of varying complexity to determine the drives where database files should be stored. Information regarding server utilization, the number of host users and the number of users in the organization is received from an administrator. The administrator input is used to calculate configuration parameters. The optimizer program may automatically adjust a plurality of registry parameters, and may automatically move one or more database and log files to the appropriate disk drives.

  • Patent number: 5812780
    Abstract: Method and system for assessing the performance of a server application that acquires performance information from the perspective of a simulated user and has significantly reduced hardware requirements. Particularly, actual user behavior is modeled so that accurate determinations can be made as to the number of users a given server application can adequately support.User behavior is modeled in a client profile that contains user parameters corresponding to the nature, timing, and frequency of user activities in operating a client that in turn corresponds to client tasks. A plurality of processes and process threads are initiated to contact a server as a plurality of simulated clients from a single client computer, each simulated client making a separate logical connection to the server. A task scheduler will schedule the simulated client tasks that are determined for each simulated user by reference to the user parameters in the client profile throughout a work day.
