Abstract:
An optical proximity sensor (5) adapted to be mounted in a liquid-jet instrument. The sensor comprises: a printed circuit (12) on which light-emitting and light-receiving elements (14, 15) are positioned to make it possible to evaluate the distance between them and a given surface; an intermediate part (16) in which the light-emitting and the light-receiving elements (14, 15) are received; and protective means (17) that cover the intermediate part. The printed circuit (12) and the intermediate part (16) are provided with through holes (18, 19) which are mutually superposed to form a passageway serving to enable the liquid to be sprayed from a liquid spray head.
Abstract:
A message doll that is easy to produce and is not required to secure a mechanism that moves an erasing magnet on the back of a magnetic display sheet and to secure a space for moving such erasing magnet. Attached to a doll (5) is a magnetic display sheet (6) having a number of microcapsules having sealed therein oily liquid, optical absorption ferromagnetic powder, optical reflection nonmagnetic powder, and anti-settling agent, and capable of having patterns such as characters written thereon on the front by a writing tool (3) having a magnet, and capable of having such patterns erased from the front by an erasing tool (4) having a magnet.
Abstract:
A pen including a marking device (1120) such as an ink jet head and a stylus (1154) for contacting the writing surface, the pen being operative to mark a visible path onto the surface, the marking device being electronically controllable to change an attribute of the path such as colour or line thickness. The pen includes a user interface such as buttons or a sliders (1404, 1406, 1408) and a display (1410) whereby a user may modify the attribute. A sensor is capable of sensing images including coded data or colour which can be stored in a memory or transmitted to an external control source. A user can select attributes by cycling or searching through stored sets thereof. Stored sets of at least one attibute being searched may be sequentially deposited in the path or displayed.

The data may relate to e.g. a colour of the to be selected and can be stored in a memory of the pen. The data may be used to calculate position and speed of the pen to identify the text written and writing speed. Alternatively an additional sensor detects position and speed or colour.
Abstract:
In this disclosure a new type of pen is described which is able to modulate the trace of the pen in response to a sensory signal of the user, such as for example skin conductance or respiration. As is known, these types of sensory signals represent the mood of the user. By changing the trace of the pen from for example blue to red, a change in mood of the user can be expressed.
Abstract:
Instrument d'écriture comportant une tête de projection (41) de liquide et une unité de traitement (6) destiné à activer la tête de projection. L'instrument comprend, en outre, des moyens de mesure (12) pour mesurer la distance entre la tête de projection et le support, et des moyens de détection de mouvement, l'unité de traitement étant adaptée pour commander l'activation de la tête de projection (41) de liquide lorsque au moins les moyens de mesure déterminent que la distance entre la tête de projection et le support est inférieure à une valeur maximale prédéterminée, l'unité de traitement étant en outre adaptée pour gérer l'activation de la tête de projection en fonction du mouvement détecté par les moyens de détection de mouvement.

Instrument d'écriture comportant un réservoir de liquide (3), une tête de projection (41) de liquide, la tête de projection étant destinée à projeter à distance le liquide sur un support (8), et une unité de traitement (6) destiné à activer la tête de projection. L'instrument comprend, en outre, des moyens de mesure (12) pour mesurer la distance entre la tête de projection et le support, et des moyens de détection de mouvement (14) de la tête de projection par rapport au support, l'unité de traitement étant adaptée pour commander l'activation de la tête de projection (41) de liquide lorsque, d'une part, les moyens de mesure déterminent que la distance entre la tête de projection et le support est inférieure à une valeur maximale prédéterminée, et que d'autre part, les moyens de détection de mouvement (14) détectent un mouvement de la tête de projection par rapport au support.
Abstract:
A holder for a writing implement, such as a ball-point cartridge, eating implements, such as a fork, a knife or like implement. The holder is arranged for holding the implement (12) and comprises means (5, 6, 8, 9) for vibrating the housing (1) with a frequency in the order of 50 to 100 Hz and an amplitude of the force causing the vibration in the order of 0.3 to 2.5 Newton. Preferably, the frequency and amplitude are adjustable. The vibrating holder enables greatly improved motor control of the implement in question for many patients.
Abstract:
A three-axis force measurement stylus includes a housing and a cartridge and an interface between the housing and the cartridge wherein the interface comprises a plurality of pressure sensitive sheets, preferably of variable resistance pressure sensitive Mylar films which sense the force between the cartridge and the housing. The cartridge and the housing are disposed at a skew angle relative to the axis of the stylus to be able to sense forces in three dimensions. In a specific embodiment, the cartridge forms a conical section which mates with a complimentary conical section of the housing. Membranes of the force sensitive material are provided along three fingers from an apex of the conical section. The cartridge is preloaded against the conical section by a spring between the housing and the cartridge. Alternatively to the force sensitive film, a sheet of a piezeoelectric pressure-sensitive material may be substituted. In each instance, direct pressure between the conical section of the cartridge and the conical section of the housing is sensed by the sensor mounted therebetween.
