Abstract: The lock with key having expanding arm elements is a lock. The lock with key having expanding arm elements comprises a body structure and a key structure. The key structure inserts into the body structure. The key structure rotates within the body structure to release the locking elements of the lock with key having expanding arm elements. The key structure comprises a plurality of rotating blade structures. Each of the plurality of rotating blade structures interact with an independent lock mechanism selected from a plurality of lock mechanisms contained in the body structure. The rotation of each rotating blade structure within its associated independent lock mechanism releases the locking elements of the lock with key having expanding arm elements.

Defibrillator monitoring units and direction prompters are installed at registered geographical locations. A defibrillator monitoring unit closest to a cardiac arrest event is identified and a subset of the one or more client devices proximate event are sent an assistance request. One of the devices sends an accept message indicating acceptance of the request an activation message is sent to the subject client device to initiate transmission of active beacon signals by the device to activating at least one of the direction prompters so as to provide geographical direction to the identified defibrillator monitoring unit or audio/visual indicators associated with the identified defibrillator monitoring unit.

Abstract: A method for detecting entrapment of an article within a laundry washing machine. The method includes rotating the drum to a target rotation speed, determining a respective drum motor torque value for each rotation, determining a distribution characteristic value of the drum motor torque values, comparing the distribution characteristic value to a predetermined threshold value, performing a correction operation to address an entrapment condition upon determining that the distribution characteristic value is above the predetermined threshold value, and proceeding with the laundry washing cycle upon determining that the distribution characteristic value is below the predetermined threshold value.

Abstract: A vehicle control device includes a recognizer configured to recognize a surrounding situation of a vehicle, a driving controller configured to control steering and acceleration/deceleration of the vehicle independently of an operation of a driver of the vehicle; and a mode decider configured to decide on any one of a plurality of driving modes including a first driving mode and a second driving mode as a driving mode of the vehicle. The recognizer recognizes a sign existing within a reference range of a route along which the vehicle travels. The mode decider changes the driving mode of the vehicle from the second driving mode to the first driving mode when the driving mode of the vehicle is the second driving mode and when the number of signs recognized by the recognizer exceeds a first reference value.

Abstract: A system for measuring the orientation angle of automotive collision avoidance sensors. An adaptive spacer is supported to conformably interengage the collision avoidance sensor module of a vehicle being repaired. The adaptive spacer extends outwardly from the sensor module and the orientation angle of the sensor module is transposed by the adaptive spacer to form an angular guideline on an underlying calibration board, mat or other surface. The angle between the angular guideline and a base guideline parallel to the center line of the vehicle and the angular guideline is measured to provide the orientation angle of the vehicle's sensor module.

Abstract: The present invention relates to a method for metallizing a front electrode of an N-type solar cell, including: treating an N-type crystalline silicon substrate to form a p+ doped region and a front surface passivation anti-reflection coating on a front surface of the N-type crystalline silicon substrate in an inside-out sequence, printing an aluminum paste on the front surface passivation anti-reflection coating to form a first finger, overprinting a silver paste on the first finger to form a second finger, and printing a front silver paste on the first finger to form a busbar. In the present invention, the superposition of the second finger on the first finger can reduce line resistance while ensuring a good ohmic contact, which further improves the photoelectric conversion efficiency of solar cells. Moreover, since no grooving procedure is required, the process is simplified and cost-efficient.

Abstract: An air-conditioning apparatus includes an outdoor heat exchanger. The outdoor heat exchanger includes a first heat exchanger and a second heat exchanger. A controller performs a heating operation and a heating-defrosting operation, in which one of the first heat exchanger and the second heat exchanger functions as an evaporator, an other one the first heat exchanger and the second heat exchanger functions as a condenser. When a temperature of the indoor heat exchanger by a temperature detection unit is treated as a first temperature, and a temperature of the indoor heat exchanger by the temperature detection unit is treated as a second temperature, the controller reduces a rotation speed of an indoor fan in a case where the second temperature is lower than the first temperature and where a difference between the first temperature and the second temperature is greater than or equal to a first setting value.

The at least one processor may be further configured to generate an aggregate preference profile based at least in part on the first preference profile, the second preference profile, and the group preference profile and to identify content items based at least in part on the aggregate preference profile. The at least one processor may be further configured to rank the content items and provide, for display on a content output device, at least one indication of at least one of the ranked content items as a recommendation for the user group.

Abstract: A method of wrapping a palletized load includes providing an apparatus with a first wrapping system and a second wrapping system, banding a top edge and bottom edge of stretch film from each of the first wrapping system and the second wrapping system, overlapping the stretch film from the first wrapping system with the stretch film from the second wrapping system to create a composite stretch film, and wrapping the composite stretch film around the palletized load. The edges of the stretch film may be banded by passing the stretch film through a set of adjustment arms. The composite stretch film may have a plurality of sections, where each section is separated from adjacent section by a banded border, a first section and third section each has one layer of stretch film, and a second section between the first section and third section has two layers of stretch film.

Abstract: A multi-factor authentication scheme uses an MFA authentication service and a browser extensionless phish-proof method to facilitate an MFA workflow. Phish-proof MFA verifies that the browser the user is in front of is actually visiting the authentic (real) site and not a phished site. This achieved by only allowing MFA to be initiated from a user trusted browser by verifying its authenticity through a signing operation using a key only it possesses, and then also verifying that the verified browser is visiting the authentic site. In a preferred embodiment, this latter check is carried out using an iframe postMessage owning domain check. In a variant embodiment, the browser is verified to be visiting the authentic site through an origin header check. By using the iframe-based or ORIGIN header-based check, the solution does not require a physical security key (such as a USB authenticator) or any browser extension or plug-in.
