Abstract: A holding device and kit for holding panels of an object. The holding device includes holding brackets which have receiving slots dimensioned to receive the panels therein. The holding brackets have holding plates which are spaced apart to form the receiving slot. Connecting members extend between the holding brackets to maintain the holding brackets in position relative to each other and maintain the spacing of the holding plates. Wherein the holding device cooperates with the panels to maintain the panels in the proper position, preventing the panels from shifting during drying and assembly, allowing the panels to be constructed in a stable and visually appealing manner.

Abstract: A water treatment cartridge has a major and a minor axis in a horizontal cross-section and mounting lugs provided at the upper end of the cartridge, generally aligned with the major axis of the cartridge.

Abstract: The invention relates to an intrusion detection process for detecting an intrusion within a space, in which at least two acoustic or electromagnetic signals are emitted at different frequencies (f1, f2, . . . fn) inside said space; at a point inside said space, a signal is received that is the combination of the signals emitted and reflected in said space; the characteristics of the demodulated signals of different frequencies are compared to establish the presence or absence of an intrusion; an intrusion signal is generated when the presence of an intruder is confirmed. The invention also proposes an intrusion detection device implementing the process according to the invention.
