Title: Attachment for hair dryers
Inventor: WILCOX JOHN
IPC: A45D20/12
Filed: 2003-12-22
Abstract: By providing a plurality of portals in a housing which forms a hair dryer attachment which is merely fixed to the exist portal of any conventional hair dryer, a hair dryer attachment is realized which is capable of substantially reducing the drying time required for drying the hair of any individual, while also being easily employed and comfortable. In the preferred embodiment, at least one raised, sloping panel is formed adjacent the inlet portal of the attachment with the panel sloping outwardly from the generally circular shaped inlet portal in addition, a plurality of apertures or portals are formed in the panel for enabling ambient air to freely flow therethrough. In this way, the heated air flowing through the central portion of the attachment creates a low-pressure zone on the inside surface of the portals, drawing ambient air through the portals into the interior of the hair dryer attachment, thereby enabling the quantity of the air reaching the hair of the user is substantially increased.

Title: Power raising circuit
Inventor: ETTORRE DONATO
IPC: G06F7/552
Filed: 2002-08-14
Abstract: An iterative power raising circuit, such as a squarer (10) comprises a module (13, 14) able to subdivide the respective input signal (Zn) into a first part (msb(Zn)) that is the power of 2 immediately lower than or equal to the input signal and a second part (Zn - msb(Zn)) corresponding to the difference between the respective input signal and the first part. A first component of the output signal is determined as the summation of squares of powers of 2 implemented by inserting zeros between the adjacent bits of the input binary signal (X). A shifter module (15) generates an additional component of the output signal through shift operations that implement multiplication operations for numbers that are powers of 2. The circuit operates according to a general iterative scheme and the number of steps in the iteration scheme is selectively controllable in order selectively to vary the precision with which the output value (Y) is calculated.

Abstract: La présente concerne un dispositif pour soulever et soutenir les fondations d'un bâtiment au moyen d'un pilier, qui comprend les éléments suivants : un premier ensemble étant fixé aux fondations, un ensemble secondaire étant assujetti au pilier à enfoncer dans le sol, puis des vérins hydrauliques reliés aux deux extrémités du premier et du deuxième ensemble. Les vérins abaissés impriment à l'ensemble secondaire un déplacement vers le bas, ce qui a pour résultat d'enfoncer le pilier dans le sol. Le premier ensemble comprend un tube guide qui oriente le pilier enfoncé dans le sol par l'ensemble secondaire et les vérins hydrauliques. Le pilier se compose d'une série de sections de pieux alignées au plan longitudinal et reliées ensemble. Après que l'extrémité inférieure du pilier a atteint une résistance suffisante sous la terre, un autre déplacement de l'ensemble secondaire provoque le soulèvement des fondations. Après le soulèvement des fondations à la hauteur voulue, le pilier est fixé au tube guide du premier ensemble, ce qui permet de soutenir et de maintenir les fondations à la hauteur voulue. L'ensemble secondaire se compose d'une paire de mâchoires opposées qui sont en prise sur le pilier au moment de l'abaissement de l'ensemble secondaire par les vérins hydrauliques. L'ensemble secondaire est pourvu d'une chicane latérale qui permet l'ajout de sections de pilier par chargement frontal.

Title: Multi-tactile display haptic interface device
Inventor: LIU ALAN V
IPC: G06F3/033
Filed: 2002-11-14
Abstract: A tactile array is integrated with a large scale force-feedback device. Under software control, the large scale force-feedback device provides large scale shape information while the tactile display provides fine structures and surface texture (410). In a virtual reality environment, the concept of a "tactile map" (420) is employed. A tactile map provides surface details and is rendered by the tactile array. Tactile maps may be based on actual object surface properties, or they may be arbitrarily generated based on the application. In operation, the effect of colliding with a object is produced and the point of contact is noted. The corresponding location on the tactile map is identified, and the surface features are rendered on the tactile array.  Moving the point of contact changes the corresponding portion of the tactile map being rendered.
