Abstract: Antimicrobial metal ion coatings and implants including them. In particular, described herein are coatings including an anodic metal (e.g., silver and/or zinc and/or copper) that is co-deposited with a cathodic metal (e.g., palladium, platinum, gold, molybdenum, titanium, iridium, osmium, rhodium, manganese, niobium or rhenium) on a substrate so that the anodic metal is galvanically released as antimicrobial ions when the apparatus is exposed to a bodily fluid. The anodic metal may be at least about 25 percent by volume of the coating, resulting in a network of anodic metal with less than 20% of the anodic metal in the coating fully encapsulated by cathodic metal. The implant may be configured as an implant such as a bone-screw or intramedullary rod-like body configured to receive a treatment cartridge having a coating as described.

Abstract: Systems and methods are described for securely distributing metadata using a block chain. The system generates a block for a distributed blockchain ledger such that the block includes an encrypted metadata item of a media asset. The system, at a first time, transmits the block for storage in the distributed blockchain ledger such that a copy of the distributed blockchain ledger is stored by the first computing device and a second computing device. The system generates a smart contract that includes a decryption key for the encrypted metadata item and an identifier of the second computing device. The system transmits the smart contract for storage in the distributed blockchain ledger. The smart contract is configured to be automatically executed at the execution time that is later than the first time, to provide the second computing device with the decryption key for the encrypted metadata item.

Abstract: A heat and humidity exchanger comprises panels made up of membrane sheets attached on either side of a separator. Channels extend across each panel between the separator and the membrane sheets. The panels are much stiffer than the membrane sheets. Panels are stacked in a spaced apart relationship to provide an ERV core. Spacing between adjacent panels may be smaller than a thickness of the panels.

Abstract: Systems and methods for establishing a voice communications link between multiple users accessing a media asset are provided. A media asset is accessed using a first user device, the first user device being associated with a first user at a first location. A second user who is accessing the media asset using a second user device is identified, wherein the second user is associated with the first user and is at a second location. A voice communications link between the first and second user devices that enables the first and second users to speak to each other while accessing the media asset is established. A volume level of audio received via the voice communications link is set based on content of the media asset, causing the audio received via the voice communications link from the second user to be presented to the first user at the set volume level.

Abstract: A linkage system is disclosed that is suitable for connecting an input shaft and an output shaft. The linkage system has a wide variety of applications, with non-limiting examples disclosed including a hinge for a door or gate, and a hub for a bicycle or similar. The linkage system comprises a first member having an input location fixedly connected to the input shaft, a second member having an input location pivotally connected to an output location of the first member, a third member having an input location pivotally connected to an output location of the second member, and a fourth member having an input location pivotally connected to an output location of the third member and having an output location fixedly connected to the output shaft. The linkage system has an engaged mode of operation whereby rotation of the input shaft causes corresponding rotation of the output shaft, and a disengaged mode of operation whereby the input shaft can be rotated independently of the output shaft.

Abstract: A no solid bed extruder screw for processing a material to a molten state has a body with a helical thread formed thereon, the thread having pushing and trailing surfaces. The body has an outer surface and extends longitudinally between feed and discharge ends. A channel for receiving the material to be processed is defined between the outer surface of the body and an outer diameter of the thread bounded by the pushing surface and the trailing surface of the thread. A volume of the channel decreases in a plurality of revolutions of the thread in a direction from the feed end to the discharge end. A channel depth between the pushing surface and the trailing surface decreases for a first portion of the channel toward the feed end and increases for a second portion of the channel toward the discharge end.

Abstract: The present invention provides an alarm system capable of monitoring and controlling access to a controlled area using a central controller and access keys each having specified permissions. The system is operable to record images or video of the access entrance areas, utilize sensors for detecting tampering with the hardware of the system; sound alarms when the rules of the alarm system are violated; send alerts to management and other authorized personnel when the rules of the alarm system are violated; and log and correlate data regarding the use of the access keys and images/video taken with the dates and times, and the identities of the access key holders to deter any misuse of the alarm system.

Abstract: A helmet for wearing by a sports player comprises: a bubble-shaped body having a hollow interior surrounded by a wall and an opening formed in the wall for inserting a head of the player, and a fastening device for releasably fastening the body to shoulder pads being worn by the player. At least a portion of the wall is formed of a transparent material. Alternate designs are also disclosed, including a helmet constructed of a plastic-coated wireframe, and a non-transparent plastic helmet with a face mask, where in all cases the helmet is rigidly but releasably attached to a chest pad or shoulder pad worn by the player, so that impact forces on the helmet are not transferred to the player's head.
