Abstract: The detector has a first optical smoke detector having a first smoke detector light source arranged for emitting a first beam of light and a first scattered light sensor positioned to detect light from the first beam which is scattered by smoke present within a detection zone; a second optical smoke detector having a second smoke detector light source arranged for emitting a second beam of light and a second scattered light sensor positioned to detect light from the second beam which is scattered by smoke present within the detection zone; and an object proximity detector to detect an object in the detection zone.

Abstract: An optical device housing has a post rotatably extending therefrom and a sleeve fixedly extending therefrom. The sleeve is disposed about the post and a knob is connected to the post. A nut rotatably engages with the sleeve and is configured to rotate with the knob. An adjustment screw is threadably engaged with the nut and engages with the knob so as to rotate with the knob. Rotation of the adjustment screw about a screw axis increases a frictional resistance between the nut and the sleeve.

Abstract: A consumption probability metric may be generated for a media asset. An aggregated forecast predicting user consumption of a media asset is received. A plurality of probabilities, each corresponding to a user of a plurality of users, is received, each indicating how likely a respective user is to consume the media asset. A weight for the plurality of users is calculated representing a ratio of the total number of users to a number of users in the plurality of users. A disaggregated forecast predicting user consumption of a media asset is determined based on the weight for the plurality of users and the plurality of probabilities. A modification factor is computed based on the aggregated forecast and the disaggregated forecast. A metric is generated that includes a plurality of user identifiers associated with the plurality of users and a plurality of modified probabilities each modified by the modification factor.

Abstract: An aiming device includes a set of lenses disposed along an optical path, the set of lenses including an objective lens and an ocular lens. A reflective element is disposed on the optical path between the objective lens and the ocular lens. An addressable display is located off the optical path and projects an image to the reflective element. The image is viewable through the ocular lens and is an aiming element superimposed on a field of view.

Abstract: Methods and systems are disclosed for an optimization system that recommends amounts of resources for use in reaching viewers during a media asset. The optimization system, using control circuitry, receives a user input of a first value of a resource and determines a first rate at which a number of unique household viewers reached during a first media asset changes for the first value. The optimization system compares the first rate to a threshold rate and determines whether the first rate equals or exceeds the threshold rate. The optimization system, in response to determining that the first rate does not equal or exceed the threshold rate, recommends a second value to the user.

Abstract: An optical device housing has a post rotatably extending therefrom and a sleeve fixedly extending therefrom. The sleeve is disposed around the post. A knob is connected to the post. A clutch mechanism includes: a friction element movably engaged with the sleeve; a friction surface; and an adjustment element engaged with the friction element and rotatable relative to the optical device housing and the knob housing. Rotation of the adjustment element selectively engages the friction surface with the interior surface.

Abstract: A medical device for wound closure, e.g., repairing perforations and tissue wall defects. The medical device has a barbed elongate body and an outer member. The medical device may further include a foam structure. The medical device may also include an inner member which may be a tissue scaffold. A method for closing tissue is also disclosed.

Abstract: Methods and systems for determining advertisement placements are described herein. The method includes retrieving a matrix of access time values, wherein each row is associated with a respective user, each column is associated with a respective media asset, and each access time value represents a length of time for which a respective user accessed a respective media source. The method includes identifying media sources accessed by a user, creating combinations of the identified media sources, and determining a minimum access value associated with each combination of the identified media sources. The method further includes creating an overlap value by adding the determined minimum access values to create an overlap value associated with each combination and selecting, based on the overlap value, a subset of a plurality of advertisement placement spots.

Abstract: The present disclosure relates to collagen-containing implants including a porous substrate having a first hydrogel precursor and a second hydrogel precursor applied thereto in a manner such that the first hydrogel precursor and second hydrogel precursor do not react with each other until the implant is placed at the site of implantation and exposed to the physiological fluids of a patient.

Abstract: The present disclosure relates to a hydrogel composition and methods of using the same. The hydrogel composition may include precursors that react with each other upon contact as well as precursors that react upon contact with an initiator. In embodiments, the resulting hydrogels may have varying levels of crosslinking with both denser and less dense regions.

Abstract: Methods and systems are provided for determining advertising reach based on machine learning. In particular, a reach calculator is provided to determine reach for advertisement campaigns in real time through the use of machine learning. The reach calculator increases the speed at which reach calculations can be done by using a trained machine learning model and a set of aggregated features as opposed to using a direct calculation approach that directly analyzes a massive amount of user data.

Abstract: A method of sighting a target includes receiving an initial condition of an optical device. The initial condition includes a size of a ranging element and a range associated with the size of the ranging element. The method further includes receiving a ballistic information and receiving an image from an imaging sensor. At least a portion of the image is displayed on a display. The ranging element is overlaid on the displayed portion of the image. A first zoom input is received to set a first zoom value that corresponds to a first distance from the optical device. The method also includes determining a first projectile position based on the first distance and the ballistic information.
