A lens unit and a camera module in which the electrical wiring extending from the electrically functional component in the lens barrel can be guided to the image side without interfering with an assembly operation, without the need of ensuring a wiring space in the lens barrel, and without forming an elongated through hole in the lens barrel. The lens barrel includes: i) a first through hole extending in the longitudinal direction inside the side wall to guide the electric wiring from the component to the image side end of the flange; ii) a second through hole extending radially on the side wall so the first through hole can communicate with the outside of the barrel; iii) an accommodation groove on the outer peripheral surface of the side wall to communicate with the second through hole, in order to accommodate the wiring and guide the wiring to the image side.

An electrical heating device comprises: a first electrode layer (13), made of electrically conductive material; a second electrode layer (14), made of electrically conductive material; and a heating layer, made of a material having a PTC effect, wherein the first electrode layer (13) and the second electrode layer (14) face one another, with at least one part of the heating layer that is set between the first electrode layer (13) and the second electrode layer (14), in contact with them. At least one region (21) of the at least one from among the first electrode layer (13), the second electrode layer (14), and said at least one part of the heating layer has a plurality of electrically non-conductive sites (30a, 30b, 30c), which are prearranged for bringing about: —an emission of heat by the heating device (10) in said at least one region (21) that is different from the emission of heat by the heating device (10) in at least one other region (22) of the at least one from among the first electrode layer (13), the second electrode layer (14), and said at least one part (15′) of the heating layer (15); and/or —an emission of heat by the heating device (10) at the first electrode layer (13) that is different from the emission of heat by the heating device (10) at the second electrode layer (14).

A flow heater for vehicles is described. The flow heater has a housing, which has an inlet and an outlet. A flow channel for fluid to be heated is disposed in the housing and leads from the fluid inlet to the fluid outlet. A heating plate forms a wall of a heated section of the flow channel and carries an electric heating resistor. A calorimetric flow sensor is provided for measuring a fluid flow in the flow channel.

A laminate comprising a base material film, a resin layer (1) having a detachable surface, and a heat-generating conductive layer in this order.

An electric resistance heating coil assembly includes a spiral wound sheathed heating element having a first coil section and a second coil section. A bimetallic thermostat is connected in series between the first and second coil sections of the spiral wound sheathed heating element. The bimetallic thermostat is spring loaded such that a distal end of the bimetallic thermostat is urged away from a top surface of the spiral wound sheathed heating element. The electric resistance heating coil assembly also includes a shroud cover and a heat transfer disk.
