Patent CA-2578531-A1 (CA)
Inventor: CERTAIN MICHAEL
IPC: H04B17/00
Filed: 2007-02-28
Abstract: A test method is for determining RF path loss between an RF source and an RF receiver. The RF source may transmit RF power values at a relatively fine granularity, and the RF receiver may generate RSSI values at a relatively coarse granularity and have an unknown hysteresis about each transition between adjacent RSSI values. Hysteresis edges may be determined about a given RSSI value transition at the RF receiver by sweeping RF power values transmitted from the RF source in increasing and decreasing directions. A relationship between the relatively fine granularity RF power values and the relative coarse granularity RSSI values may be determined using the hysteresis transition edges. The RF path loss for a given channel may be determined based upon a given RSSI at a given RF power value and the relationship between the relatively fine granularity RF power values and the relative coarse granularity RSSI values.

Title: Improved mortar compositions with base on ultra-fine clinker, refined sand and chemical additives
Inventor: GARCIA LUNA ARMANDO
IPC: C04B28/04
Filed: 2005-06-02
Abstract: The invention describes improved mortar compositions that can reach compressive strength values up to six times more than the obtained ones by conventional mortars at the first hours of setting, as well as up to three times more at 28 days of setting. Cementitious materials, such as Portland cement and clinker of Portland cement were refined in a high energy mill until reaching the greater fineness possible (100% < 10,um) to obtain a material with greater mechanical resistance by compression that those that are reached with normal cement. The compositions of the invention containing the refined cementitious material as well as refined and suitably distributed sand, develop compressive strengths substantially higher (greater to 100 MPa).

Title: Disposable wall box painting mask
Inventor: VAN DE WIELE CHARLES E JR
IPC: B05C17/06
Filed: 2007-03-01
Abstract: A mask for use during painting shields those components of the contents of a wall box which will be exposed through a decorative plate used to cover the wall box after the wall is painted. The mask is a substantially flat thin sheet with an adhesive substance applied to its face along its outer perimeter for adhering the sheet to the wall. The substance may be continuous or may be spotted about the perimeter. A pad of identical masks can be temporarily held in stacked laminar relationship by the adhesive substance. The mask may also have a raised portion of perimeter, depth and location suitable for shielding any of the contents of the box which protrude from the box beyond the plane of wall surface. The raised portions may be tapered to facilitate nesting of identical masks in a pad temporarily held in stacked laminar relationship by the adhesive substance.

Filed: 2007-05-16
Abstract: The steam turbine plant includes an extraction system 3 (3a, 3b) which extracts a portion of main steam from an intermediate stage of a steam turbine 1 and delivers the extracted steam to a demander 8 and a steam extraction control system 7 for controlling the steam extraction. The extraction system includes an extraction steam flowmeter 5 (5a, 5b) and an extraction steam stop valve 6 (6a, 6b). The control system can set a warning flow and an extracted steam stop flow as restrictive flow values with respect to a flow of the extracted steam. When an extracted steam flow measurement value from the flowmeter reaches the warning flow, a warning is issued and after a lapse of a predetermined time period the stop valve is brought into a fixed open state for restriction of the extracted steam flow. When in the restriction state the extracted steam flow is further increased and the extracted steam flow measurement value reaches the extracted steam stop flow, the stop valve is fully closed for stoppage of steam extraction. With such features, a steam turbine plant can exercise extraction control capable of stably supplying extracted steam while it is primarily intended that the turbine can continuously be operated by avoiding occurrence of the turbine trip due to steam extraction even if it is not equipped with a high- performance and expensive valve device such as an extraction steam control valve and adopts high-pressure steam condition.

Title: Hybrid portrait-landscape handheld device with trackball navigation and qwerty hide-away keyboard
Inventor: GRIFFIN JASON T
IPC: H01H13/70
Filed: 2007-08-28
Abstract: A device is disclosed for use in two different orientations. In one orientation, the keyboard is exposed to the user. This orientation is named the landscape orientation because the device will be positioned such that its width is larger than its height. The user would opt for the landscape orientation for tasks that require the keyboard, such as inputting data, drafting emails, sending emails, and other functions typically associated with a standard computer. The other orientation is named the portrait orientation because the device will be positioned such that its height is larger than its width.  In addition, the keyboard is not used in this orientation and therefore hidden away. The user would opt for the portrait orientation for tasks such as making and receiving telephone calls and for reading documents and emails. The device detects the orientation positioned by the user and modifies the elements shown on the display screen so that they are presented in the correct orientation to the user.
