Fabrication of low defectivity electrochromic devices
Prior electrochromic devices frequently suffer from high levels of defectivity. The defects may be manifest as pin holes or spots where the electrochromic transition is impaired. This is unacceptable for many applications such as electrochromic architectural glass. Improved electrochromic devices with low defectivity can be fabricated by depositing certain layered components of the electrochromic device in a single integrated deposition system. While these layers are being deposited and/or treated on a substrate, for example a glass window, the substrate never leaves a controlled ambient environment, for example a low pressure controlled atmosphere having very low levels of particles. These layers may be deposited using physical vapor deposition. |

Determining matches using dynamic provider eligibility model
Embodiments provide techniques, including systems and methods, for determining matches of requestors and providers based on a dynamic provider eligibility model. For example, a request matching model uses an estimated arrival time for a requestor and estimated travel times for available providers to a pickup location to determine eligible providers for matching to a ride request. The matching model determines those providers that are far enough away from the request location to allow the requestor time to arrive at the pickup location without matching providers that are too far away, causing delay for the requestor and lowering the efficiency of the system by taking provider system resources from other service areas and increasing provider downtime upon matching. Additionally, embodiments provide more efficient matching processing leading to fewer canceled matched requests, fewer requests for a successful match, and fewer system resources necessary to meet requestor demand. |

Support for risers and method for coupling and uncoupling
The present invention addresses to a system for supporting the tension load of the riser, this component with the primary function of supporting the risers, where the riser support mechanism is an integral part of the upper cone, thus eliminating the need to install slips by the shallow dive, and, also avoiding that the locking mechanism is an integral part of the Top Termination of the Riser (L). There is a minimal number of moving parts, which favors the maintainability of the system. In addition, if maintenance is required, the size and weight of the components are compatible with diving operations. For pull-in operations, it is anticipated that the slips will return to their working position only by the action of the force of gravity. In the case of pull-out, the concept of automated slip retraction mechanism was developed. A new Top Termination of the Riser (TTR) (L) geometry is also proposed, aiming at its simplification, in which, in addition to considering the locking mechanism as an integral part of the upper cone of the Support Pipe, there is the elimination of moving components for stabilization of its side movement (a function formerly performed by the locking ring or by the gap compensator). |

Low-power radio-frequency receiver
A low-power radio-frequency (RF) receiver is characterized by a decreased current consumption over prior art RF receivers, such that the RF receiver may be used in control devices, such as battery-powered motorized window treatments and two-wire dimmer switches.

The RF receiver compares detected RF energy to a detect threshold that may be increased to decrease the sensitivity of the RF receiver and increase the lifetime of the batteries. After detecting that an RF signal is being transmitted, the RF receiver is put to sleep for a snooze time period that is longer than the sleep time and just slightly shorter than the time between two consecutive transmitted packets to further conserve battery power. |
