Abstract: A portable hoisting device configured to be connected to a cable secured to a destination location for hoisting at least one person from a start location to the destination location is provided. The device includes a winch mechanism having a drum body shaped and adapted to have the cable wrap around the drum body. The winch mechanism is operable to selectively wrap the cable around the drum body. The device has a gear train operatively connected to the drum body and operable to engage the drum body in rotation, a motor operatively connected to the gear train, a control assembly operatively connected to the motor to control same, and a latching assembly adapted to enable a load to be connected to a component of the portable hoisting device, wherein the control assembly comprises a remote control configured to send signals to the motor remotely.

Abstract: According to one aspect, the present invention concerns a terahertz modulator (1) intended to be used in a given frequency band of use. The modulator comprises a semi-conductor polar crystal (330) presenting a Reststrahlen band overlapping said frequency band of use and presenting at least one interface with a dielectric medium, coupling means (330) allowing the resanant coupling of an interface phonon polariton (IPhP) supported by said interface and of an incident radiation (2) of pre-determined frequency lying in said frequency band of use and means of control (22) apt to modify the intensity of the coupling between said interface phonon polariton and said incident radiation (2) by modification of the dielectric function of the polar crystal in the Reststrahlen band of the polar crystal (10).

Abstract: According to a first aspect of the invention, the invention relates to a terahertz detection cell for detecting radiations having frequencies within a given spectral detection band, said cell comprising: a polar semi-conductor crystal structured such that it forms at least one slab of crystal, said crystal (330) having a Reststrahlen band covering said spectral detection band, and comprising at least one interface with a dielectric means; coupling means obtained by the slab structure (330), each slab forming an optical antenna, enabling the resonant coupling of an interface phonon polariton (IPhP) supported by said interface and an incident radiation having a frequency within the spectral detection band; and at least one first and one second connection terminal (301, 302) that are in electrical contact respectively with a first and a second end of the interface, said ends opposing each other, and said connection terminals to be connected to an electrical reading circuit for measuring the variation of the impe

Abstract: Techniques for providing users with packaging and/or shipping materials may include receiving an optical image of an object having starting and shipping locations or keywords associated with the object; comparing with an optical recognition program, the optical image of the object to images of objects within a database of objects to identify the object, or the keywords in the search bar with words used in a description of objects in a database of objects to identify the object; assigning packaging and/or shipping information to the identified object; and ordering the packaging and/or shipping materials for the identified object and optionally supplying the packaging and/or shipping materials to the user at the starting location. Various related processes, systems and apparatuses are also provides.
