Abstract: The subject matter discloses a computerized method for introducing persons, comprising receiving a request from an introduction generator, generating a list of potential target persons that match the request, each of the potential persons is associated with a mediator, said mediator is a mutual contact of the introduction generator and the person of the potential persons, receiving a selection from the introduction generator, said selection comprises a selected potential person and a selected mediator and creating a mutual conversation at a computerized device used by the selected mediator, said mutual conversation enables the selected mediator to simultaneously converse with the selected potential person and the introduction generator.

Abstract: Devices for monitoring one or more parameters of a subject, and related methods and systems, are disclosed. The device comprises a support element configured and arranged to detachably attach over a skin region of a chest area of a subject, an optical sensor assembly mounted to said support element and configured and arranged to conduct optical measurements in said chest area and generate optical measurement data indicative of said one or more parameters of said subject, a volumetric sensor assembly mounted to said support element and configured and operable to measure chest expansions and retractions of said subject and generate volumetric measurement data indicative of the expansions and retractions of the chest of said subject, and a control unit mounted to said support element and configured and operable to process said optical and volumetric measurement data for removing interferences introduced into said optical measurements due to said chest expansions and retractions.

Abstract: Massager vehicle for autonomously traveling on the body of a patient, The massager vehicle is massaging the body of the patient, the massager vehicle includes a vehicle chassis, at least one motor, at least three wheels, a roll tilt sensor, a pitch tilt sensor, a boundary sensor and a controller, The at least three wheels are coupled with the chassis, at least one of the wheels is positioned at a first side of the chassis and at least another one of the wheels is positioned at a second side of the chassis, opposite to the first side, the roll tilt sensor determines a roll angle of the massager vehicle, the pitch tilt sensor determines a pitch angle of the massager vehicle, the boundary sensor determines when the massager vehicle is approaching a boundary, beyond which the massager vehicle may not travel, the controller controls the motion of the massager vehicle the controller is coupled with the motor, the roll tilt sensor, the pitch tilt sensor and with the boundary sensor, the controller receives informati
