Title: A method and an arrangement relating to temperature sensing in electric circuitry
Inventor: KELLERMAN MICHAEL
IPC: H01M10/48
Filed: 1999-08-20
Abstract: It is shown a method and an arrangement for determining a temperature of a battery pack (100) connected via a single communication line (107) to an electric device (101). The battery pack (100) and electric device (101) both comprise control and signaling means (105, 108) capable of exchanging digital signal sequences. The battery pack (100) comprises an impedance unit (112) having a temperature dependent impedance value. The method comprises steps of signaling between the battery pack (100) and the device (101). This is followed by a sequence of steps where the control and signaling means (105) of the battery pack (100) is disconnected from the communication line (107) and the temperature dependent impedance unit (112) is connected to the communication line (107). Electric current is supplied to the impedance unit (112) via the communication line (107) and a voltage level is measured on the communication line (107). Then an impedance value is calculated based on the supplied current level and the measured voltage level. An interpretation of the calculated impedance value as a temperature of the battery pack (100) is then performed, followed by disconnecting the temperature dependent impedance unit (112), and reconnecting the control and signaling means (105) of the battery pack, to the communication line (107).

Patent CA-2358839-A1 (CA)
Inventor: HAAS JEAN
IPC: A01G9/10
Filed: 2001-10-11
Abstract: The present invention relates to a potting system for use with plants, and in particular for using a rock material in a novel potting arrangement and method for improved water and nutrient delivery to potted plants. The present system has two general aspects: the standard soil based growing medium in which the root ball of the plant sits; and, a reservoir for fluid that is continuously supplied to the plant via capillary action. This fluid is contained in a layer of inert, pH neutral pumice volcanic rock that has preferably been thoroughly washed. Due to the porosity and pore structure of the pumice material, it exhibits strong capillary action properties. This layer of pumice rock sits beneath the root ball of the plant in the base of the pot which lacks drainage holes. An overflow hole may be added a distance above the base of the pot to prevent drowning the root ball. Alternately, the plant, soil and pumice may be housed in a meshed bottom basket which may be inserted within the pot.

Title: Ion mobility spectrometer incorporating an ion guide in combination with an ms device
Inventor: LOBODA ALEXANDER V
IPC: G01N27/64
Filed: 2001-12-07
Abstract: A hybrid mass spectrometer comprises an ion mobility (IMS) section and a mass analysis section that analyses ions based on mass-to-charge ratios.  In the IMS section, a DC potential gradient is established and a drift gas provided, so as to separate ions based on varying ion mobilities. Additionally, at least a downstream portion of the IMS section includes a rod set focusing ions along the axis, this prevents loss of ions and gives good transfer of ions into-a-mass analysis section, which can be a time-of flight mass analyzer or an analyzer including a quadrupole rod set. A collision cell and mass analyzer can be provided between the two sections for MS/MS analysis. The IMS section then provides better utilization of an available sample; as each group of ions is elected from the IMS section, one ion can be mass selected as a precursor, for subsequent fragmentation/  reaction and subsequent mass analysis of the product ions. Another aspect of the invention provides the ability to form potential wells, utilizing a segmented rod set configuration, so as to trap and hold ions after separation based on mobility characteristics.

Title: Modular pontoon system
Inventor: RICE THOMAS
IPC: B63B35/38
Filed: 2001-12-24
Abstract: A pontoon composed of a series of hollow pontoon elements which when mounted on a pair of guide rails becomes an integral assembly forming a pontoon. The elements, with the exception of the bow and the stern elements, are identical, with the stern and bow elements having a curved water engaging surface to decrease the resistance to passage through the water. The pontoon elements are mounted between a pair of metallic channels where they may be suitably fastened during use. A screw jack or cable may be used to apply a compressive force to the various pontoon elements to form an integral pontoon assembly. The mounting system used securing for the various pontoon elements to the channel members permits easy removal of a damaged element and swift installation of a suitable replacement element without having to remove the complete pontoon assembly from the craft on which the pontoon is mounted. The pontoon system may be advantageously used for watercraft (houseboats, floating and moving barges), bridges and float assemblies for aircraft.

Abstract: A catheter assembly (10) is provided with a rotational and translational drive coupling (26) and an insertion section (14), which includes a sheath (16) and a core (18) slidably housed within the sheath. The drive coupling (26) includes an elongate rotary drive element (36), defining a first longitudinal drive path, mounted for rotation about a longitudinal axis (42). A termination element (44) is mounted to the proximal end of the core (18) and slides along the first longitudinal drive path but rotates with the rotary drive element (36). A bearing (46) has an inner race (48) secured to the termination member and an outer race (50) coupled to the longitudinal drive element (54, 62) of a longitudinal driver (56). Rotation of the rotary drive element (36) rotates the termination element (44) and the proximal end of the core (18) therewith about the longitudinal axis (42). Longitudinal movement of the longitudinal drive element (54, 62) translates the bearing (46) parallel to the longitudinal drive path; this causes the termination element (44) and the proximal end of the core (18) therewith to be translated along the first longitudinal drive path, the translational and rotational movements being independent of one another.

Title: A development framework for efficient uniform control of heterogeneous communication networks
Inventor: ZINE EL-ABIDINE KHALDOUNE
IPC: H04L12/24
Filed: 2002-04-03
Abstract: As new Internet networking technologies appear, there is a growing need for efficient control of Network Elements (NE) (i.e. routers, switches, etc:).  However, today's NE control is largely a manual activity, therefore inefficient and unscalable, and the inherent heterogeneous nature of complex networks -that is, the fact that NEs are of different technologies and have different functionality and configuration-management interfaces- makes NE control even more difficult and challenging. This thesis presents a solution that allows the development of automated, distributed web-based control of heterogeneous NEs through a common interface that hides the underlying NE-specific differences, allowing control of heterogeneous NEs in a transparent way. This solution consists in a software development framework oriented towards reliability -thus service availability-, performance -hence scalability-, and fast extensibility -hence easy integration and rapid adaptability to the ever-changing networking technologies-, without neglecting security. General design requirements are first discussed. Next, particular attention is given to CLI (Command Line Interface) protocols, where issues related to the automation of CLI interaction are extensively discussed. A real-time approach, using extended finite state machines, is proposed as a key element in this framework. Finally, a working and efficient implementation that supports CLI automation is presented, where emphasis is laid upon the short delays -typically a day- required to augment the application with a new set of NE control operations -Traffic Conditioning operation set for example.
