Title: Cleaning implement to improve particulate pick-up and minimize residue left on surfaces and cleaning implements for use with cleaning sheets
Inventor: CLARE BENJAMIN J
IPC: A47L13/24
Filed: 2001-02-23
Abstract: Cleaning sheets comprise an additive that is selected to enhance the pick up and retention of particulate material from surfaces, while minimizing the amount of residue left on the surface being cleaned. If the type of additive and level of additive on the cleaning sheet are not carefully selected, the sheet will leave a residue on the surface being cleaned resulting in filming and streaking of the surface that is unacceptable to consumers. The additive is preferably selected from the group consisting of a wax, an oil, and mixtures thereof. Cleaning implements comprise a mop head having a resilient bottom surface, a portion of which preferably has a substantially smooth curved profile or crown which engages a removable cleaning sheet.

Abstract: An improved valve (100) for use in a heavy vehicle pneumatic braking and parking system is disclosed. The valve includes a solenoid coil assembly (110), a valve seat (122), an armature (130), and a spring (150). The solenoid coil assembly includes a pole piece (112) and produces a magnetic field when energized. The valve seat (122) has a valve seat surface and defines a flow passage (126). The armature (130) has a first end (132) and a second end (134) and includes a spherical shaped elastomeric seal (140) sized to engage the valve seat (122) to block air flow through the flow passage (126). The spring (150) is engaged around an exterior of the armature (130) and resiliently biases the armature (130) toward the valve seat (122). When energized, the solenoid coil (110) displaces the armature (130) to an open position away from the valve seat (122) and toward the pole piece (112) to allow air flow through the flow passage (126).

Title: Analysis of multi-channel measurement data using orthogonal virtual channels
IPC: A61B5/296
Filed: 2007-06-13
Abstract: The present invention introduces a method for processing multi-channel measurement data achieved especially in MEG and EEG measurements. The method uses a signal space separation (SSS) method and the orthogonality of lead fields in order to calculate linear transformation from physical measurement channels to virtual channels. The geometry related to the measurement arrangement is dissipated and the number of virtual channels is clearly lower than the number of physical sensors. The concept of total information can be applied for such transformed measurement data due to orthogonality. The method offers simplified post-processing of the bio-magnetic data, such as for source modelling. The total information can also be interpreted as a robust quantity describing the physiological state of a patient.

Title: Handheld mobile communication device with moveable display/cover member
Inventor: LADOUCEUR NORMAN M
IPC: G06F15/02
Filed: 2007-07-19
Abstract: Handheld mobile communication devices according to the disclosure have a closed position, in which the display member of the device covers at least a portion of the keys of on the keypad member of the device, and an open position, in which the keys are accessible and the device is operated. When the display member is in the open position, it forms an ergonomically desirable angle (e.g., on the order of about 155 ) relative to the keypad member. However, unlike clamshell-type cellular phones, the display member does not simply flip open about a conventional pivot joint. Rather, it moves from the closed position, where it is parallel and adjacent to the keypad member, to the open, angled position through a sliding/sweeping motion; through an eccentric, "up-and-over"  rotational motion; or through a combination sliding/"up-and-over" motion.

Title: Waterfall unit
Inventor: SCALI IAN P A
IPC: B05B17/08
Filed: 2007-10-24
Abstract: A waterfall unit for use in a spa includes a body defining a bowl, a beveled arcuate outer edge surface which curves over the bowl and a water entrance port in communication with the bowl.  The water entrance port is located in the bottom of the bowl. A deflector cap is spaced away from and over the water entrance port. Water flows upwardly through the water entrance port in a fountain-like manner. This water contacts the deflector cap which deflects the water and causes it to flow laterally and into the bowl. When the bowl fills with water, the water flows over the beveled outer edge surface to create a waterfall. The body further defines a flat back wall for mounting the waterfall unit against a spa wall. The body has a substantially curved body profile formed by the bowl and the beveled outer edge surface.
