Abstract: A torque tool for welding regulator gages includes a wrench body, a retention pin, and a tab. The wrench body is configured with a handle and a wrench-head. The handle is externally and laterally connected to the wrench-head as torque is applied through the handle. The wrench-head is engaged with the inlet fitting of the welding regulator gage so that the gage can be removed from or attached to the gas cylinder.

A plurality of covers is each hingedly disposed on the pill box for opening and closing the compartments. A lid is hingedly coupled to the pill box for opening and closing the pill box. A weight sensor is integrated into the pill box to sense weight of the pills in the compartments. An alert is integrated into the lid and the alert is in communication with the weight sensor. The alert is actuated when the weight sensor senses a weight that is below a pre-determined trigger weight to communicate that the number of pills in the compartments has fallen below a minimum amount.

Abstract: Prefetch of microservices for incoming requests. The method determines for an incoming request a Service Level Objective (SLO) requirement for latency of a request type of the incoming request. The method generates a set of possible microservice sequences for the request including a probability of occurrence of each of the possible microservice sequences and determines a set of prefetch permutations for the set of possible microservice sequences. A latency score is calculated for each prefetch permutation and any prefetch permutations that do not meet the SLO requirement for latency of the request type are eliminated. An optimal prefetch permutation of the remaining prefetch permutations is selected by considering a total cost of the prefetch permutation based on a cost of running each microservice in the set of sequences.
