  • SYSTEM AND METHOD TO TRACK USAGE OF SURGICAL INSTRUMENT
    Publication number: 20240180580
    Abstract: Systems, devices, and methods are operable to track usage of a surgical instrument and modify the performance of the surgical instrument based on the prior usage of the surgical instrument. Some surgical instruments are designed to have a limited service life beginning at their first use, or a limit to their overall usage in order to ensure safe use of the sensitive instruments. However, a lack of ability to track usage characteristics when the instrument is separated from an external power supply allows for user abuse and avoidance of such safety mechanisms. Adding a battery or capacitor to the instrument may allow for an ability to track usage when the instrument is separated from an external power supply. Implementing special user prompts, device use ratios, and device use half-life upon powering down of an instrument may additionally be used to prevent circumvention of safety features.

  • Pyroglutamic acid esters, their synthesis and use in topical products
    Patent number: 4774255
    Abstract: Esters of pyroglutamic acid having the structure: ##STR1## where R' and R" are the same or different and are each represented by H or the groupingCH.sub.3 [(CH.sub.2).sub.w (CHCH.sub.3).sub.x (CHOH).sub.y (CH.dbd.CH).sub.z ]--wheren is an integer of from 1 to 3w is zero, or an integer of from 1 to 21x is zero, or an integer of from 1 to 4y is zero, or an integer of from 1 to 2z is zero, or an integer of from 1 to 4provided that the total number of carbon atoms in each of said grouping will not exceed 22;and provided also that when the subgrouping (CH.dbd.CH) is present, then the total number of carbon atoms in said grouping will be from 16 to 22. Synthesis, and uses of the said esters in topical compositions are also provided.
