Abstract: A hydraulic valve comprises a proportional piloted valve that controls pressure and includes means for restricting pilot flow through the pilot flow passage. The means for restricting pilot flow defines a restriction in the pilot flow passage when a movable spool disposed in an axial bore of the body of the valve is in a neutral position. The restriction varies as a function of spool movement such that flow of hydraulic fluid through the pilot flow passage is variably restricted as a function of the position of the spool over its range of travel.

Abstract: A modular illumination and aiming apparatus, an example of which includes an optical head module, mounting module, and an end cap module. The modular illumination and aiming apparatus is configured to be quickly and intuitively adjusted by a user in response to changing target and environmental conditions. The modular illumination and aiming apparatus is configured to be ergonomically supportive such that a user may maintain a consistent firing grip while activating the illumination and aiming functions. The optical head module is configured to allow the user to change radiation types by adjusting an end cap. The alignment mechanism in the optical head module for the radiation source and optics is configured to provide a robust and zero-play optical mount in order to resist recoil and general physical shock.

Abstract: An embodiment of a support structure for adjusting the position of a plurality of optical elements is described that comprises a base plate comprising a centering pin, a first translation slot, and a second translation slot; and a translatable plate configured to operatively couple with a plurality of the optical elements and move relative to the base plate, wherein the translatable plate comprises a centering slot configured to engage with the centering pin, a first cam configured to engage with the first translation slot and control movement of the translatable plate along a first axis, and a second cam configured to engage with the second translation slot and control movement of the translatable plate along a second axis.

Abstract: Processes and systems for lessening human spread of coronaviruses can include use of a disinfectants and/or rinses that utilize contact times of up to 2 minutes or less than 2 minutes and also more than 20 seconds. Some embodiments can include gargling a rinse having at least one disinfectant as an active ingredient for up to 2 minutes or for a time period of less than 2 minutes. Other embodiments can include performing a naso-rinse for up to 2 minutes or a time period of less than 2 minutes and also more than 20 seconds with rinse fluid having at least one disinfectant.

Abstract: A system for applying access permissions to read requests may write a file to a storage media. The file may contain data, an embedded flag, and an embedded verification datum of the embedded flag. The embedded flag may indicate an access permissions requisite for file access. The system may also receive a request to access the file from a user and retrieve an access permission for the user. The system may also compare the embedded flag to the access permission for the user to determine the user has permission to access the file. A verification datum may be calculated, and the calculated verification datum may be compared to the embedded verification datum to determine the embedded flag has not changed.
