Abstract: Provided is a technology for supporting solution of a fault that has occurred in a system including an audio-visual device. A solution support program storage unit (7) is configured to store, for each potential fault, a solution support program for supporting a user's job for solving the each fault. At least one of the solution support programs for handling a fault having a plurality of possible causes includes processing for displaying a message for prompting the user to conduct a predetermined job, processing for displaying a question for the user, processing for receiving a user's answer to the question, and processing for displaying a message indicating a solution corresponding to the received answer. Then, a main control unit (9) determines a fault based on the information acquired through an audio-visual signal input interface unit (3) and an audio-visual signal output interface unit (4), and executes the solution support program for handling the determined fault.

Abstract: Hematopoietic stem/progenitor cells (HSPC) and/or non-T effector cells are genetically modified to express (i) an extracellular component including a ligand binding domain that binds a cellular marker preferentially expressed on an unwanted cell; and (ii) an intracellular component comprising an effector domain. Among other uses, the modified cells can be administered to patients to target unwanted cancer cells without the need for immunological matching before administration.

Abstract: The invention relates to a device (5) comprising: —an optical surface (10); —a cleaning unit (15) for cleaning the optical surface, comprising at least one wave transducer (70) acoustically coupled to the optical surface, the wave transducer having a piezoelectric layer (80) and electrodes (85) of opposite polarity in contact with the piezoelectric layer, and being configured to generate at least one surface ultrasonic wave (WS) or a Lamb wave (WL) propagating in the optical surface; —the optical surface having at least one region of optical interest (100) not superposed on the wave transducer, the device comprising an apparatus (20) configured to sense and/or to emit radiation (R) through the region of optical interest (100).

Abstract: A rifle has a fixed main body including a barrel, a receiver with an upper opening, and a breech element. A carriage assembly is axially movable between an advanced shooting configuration and a retracted rearming configuration, and vice versa. The carriage assembly includes an assembly body positioned on the receiver at the upper opening, which is axially slidably movable, having a through housing extending transversally, a firearm handle with an outer portion grippable and an inner portion shaped for complementarily housing in the through housing, being insertable both sides, and a shutter group partially accommodated in the assembly body, including a shutter body and a shutter head. The shutter head is mountable onto the shutter body in first and second angular positions, which are reciprocally inverted. The rifle is configurable for a right-handed or a left-handed person by changing the position of the firearm handle and the shutter head.

Abstract: Target devices for characterizing terahertz imaging systems are provided. The target devices include a terahertz resolution pattern having spatially distributed resolution features and one or more prism assemblies configured to provide a variable contrast level within the resolution features when used with terahertz radiation. Each prism assembly includes first and second prisms arranged in a Frustrated Total Internal Reflection (FTIR) configuration.

Abstract: A wiper arm and assembly are disclosed. The wiper arm has a wiper arm holder, connected at one end to an output portion of a driving mechanism for the wiper arm that drives the wiper arm to swing back and forth in an outward-swinging direction, an extension arm pivotally connected to the other end of the wiper arm holder, a wiper arm end member located on the side of the wiper arm opposite to the wiper arm holder and configured to hold a wiper blade, and a washer assembly having at least a first nozzle, and a first conduit in fluid communication with the first nozzle. The first nozzle includes a nozzle unit, a first connector for the first conduit, and a bridge channel located between them, above the blade. The bridge channel is partially aligned with a segment of the wiper arm end member that is located above the blade.
