Patent CA-2832767-A1 (CA)
Inventor: DAHLSTROM MATTIAS
IPC: A61C8/00
Filed: 2012-04-19
Abstract: According to an aspect of the invention, in a set of male dental components, such as abutment screws, each male dental component has a threaded portion with different core diameter. Each male dental component is to be connected to a mating female dental component, such as an abutment. The smaller core diameter a threaded portion has, the higher friction is provided when the male dental component is finally tightened to its mating female dental component, even though the same insertion torque is applied to all male dental components.

Abstract: According to one aspect, a request is received at a services application programming interface (API) of a support center from a user for support services of a product. A first list of one or more communication channels that are available for the user to contact an agent of the support center is generated based on a second list of one or more communication channels preferred by the user and a third list of one or more communication channels preferred by a vendor associated with the product. The first list of one or more communication channels is transmitted via the service API to the user. In response to a selection of a communication channel from the first list, a communication session is established between the user and the agent via the selected communication channel for providing support services of the product on behalf of the vendor.

IPC: A61M25/00
Filed: 2012-06-21
Abstract: This disclosure is directed to systems and methods for providing a guiding device having a dilatable, drilling tip. The tip is formed by wound helical members such that resistance to rotation in an unwinding direction dilates the tip. The helical members are configured so that the dilatable tip increases in stiffness when the helical members are tensioned by a resistance to rotation in the winding direction. In some embodiments, application of relative force between coaxial inner and outer tubular members is used to control the dilation, stiffness and drilling of the guiding member.

Abstract: In a multi-sensing, wirelessly communicating learning thermostat that uses power-harvesting to charge an internal battery, methods are disclosed for ensuring that the battery does not become depleted or damaged while at the same time ensuring selected levels of thermostat functionality. Battery charge status is monitored to determine whether the present rate of power usage needs to be stemmed. If the present rate of power usage needs to be stemmed, then a progression of performance levels and/or functionalities are scaled back according to a predetermined progressive power conservation algorithm. In a less preferred embodiment, there is a simple progressive shutdown of functionalities turned off in sequence until the desired amount of discharge stemming is reached. Battery charge preservation measures are also described for cases when an interruption of external supply power used to recharge the battery is detected.

In an embodiment, a driving shoe (316, 316) has a perimeter that extends beyond the pile tube such that the sediment produces less of a binding force on the pile. The pile may be formed as a double-shelled pile (310) with either or both shells having effective low Poisson's ratio properties. A bubble generating plenum (328) may be attached to the shoe to further reduce friction during installation.
