  • Patent number: 11510669
    Abstract: A hand-held surgical instrument includes a handle housing, an elongated shaft portion configured to extend distally relative to the handle housing, and a surgical end effector configured to be coupled to a distal end portion of the shaft portion. An articulation screw is operably coupled to the surgical end effector, and an articulation nut is disposed about and operably coupled to the articulation screw. The articulation screw is configured to translate in response to a rotation of the articulation nut, whereby the articulation screw articulates the surgical end effector between a parallel orientation relative to the shaft portion and a non-parallel orientation relative to the shaft portion.

  • Patent number: 11498716
    Abstract: A method of applying a linerless label to an article wherein a web of joined labels is die cut from a web of label material in which the adhesive is protected by a water-soluble coating which provides a cushion between an anvil and die cutting means. The water-soluble coating is at least partially removed by exposure to water in a press following die-cutting, in a label applicator, or in an off-line unit. The web of joined labels may be wound and unwound between each of the above options. The web of joined labels may be separated in a label applicator by breaking a weakened boundary between adjoining labels or by cutting at a boundary between the label and the adjoining label. The linerless label may contain anti-counterfeit means that may be subsequently identified overtly and/or covertly.

  • Patent number: 11496519
    Abstract: Security can be provided for data stored using resources that are deployed in an environment managed by a third party. Physical and logical detection mechanisms can be used to monitor various security aspects, and the resulting security data can be used to identify potential threats to these resources. In some embodiments, suspicious activity can cause resources such as data servers to be automatically and remotely rebooted such that keys stored in volatile memory on those data servers will be lost from those servers, such that an attacker will be unable to decrypt data stored on those servers. Once a determination of safety is made, the keys can be provided to the respective data servers such that data operations can resume.

  • Publication number: 20220304320
    Abstract: A traditional method for making, pasteurizing and packaging preservative-free, fresh food product comprising chickpeas, such as hummus, that involves a continuous process in which the temperature does not deviate more than 50° C. from the cooking step until just prior to packaging. In one embodiment, the method comprises cooking the chickpeas from 110° C. to 125° C. while under pressure, which is followed by adding raw ingredients to the cooked chickpeas at a temperature ranging from 75° C. to 85° C., which is immediately followed by a pasteurization at approximately 75° C. Only after this pasteurization step is the temperature reduced in a multi-step cooling process. The as-made, fresh and preservative-free food product comprising chickpeas, such as hummus, is packaged into containers by transferring the finished food product that is maintained at a temperature ranging from 5° C. to 10° C.

In one embodiment, the method comprises cooking the chickpeas from 110° C. to 125° C. while under pressure within the closed vessel, which is followed by adding raw ingredients to the cooked chickpeas at a temperature ranging from 75° C. to 85° C., which is immediately followed by a pasteurization at a temperature ranging from 70° C. to 80° C., such as approximately 75° C. Only after this pasteurization step is the temperature reduced in a multi-step cooling process. A fresh, preservative-free, fresh food product comprising chickpeas, such as hummus made according to the present method is also disclosed.
