Abstract: Hydrogen-producing fuel cell systems and methods of operating the same. The methods include initiating supply of a stored hydrogen stream, which includes stored hydrogen gas, to a fuel cell stack. Prior to the initiating, the stored hydrogen gas is stored in a low-pressure hydrogen storage tank at a hydrogen storage pressure. The methods also include generating an electrical power output from the stored hydrogen gas with the fuel cell stack. The methods further include, during a supply time interval that is subsequent to the initiating, monitoring a hydrogen supply variable that is indicative of flow of the stored hydrogen stream to the fuel cell stack. The methods also include detecting a change in the hydrogen supply variable and responding to the detecting. The systems include a controller that is programmed to perform the methods.

Abstract: The “telltale” of an outboard motor is a feature that signals to the operator that the cooling system is working properly. The narrow passage of the telltale can easily become clogged. The telltale clearing tool of the present invention comprises an attachment mechanism, a float, and a path-clearing mechanism. The attachment mechanism allows the tool to be secured to a variety of locations on a boat for easy access when the tool is needed. The float ensures the tool will not sink if dropped in the water. The path-clearing mechanism is flexible enough to traverse the narrow passage of the telltale, but not so rigid as to puncture or tear the tubing, and further is of sufficient length to clear most clogs, but not long enough to enter and/or damage the fuel cooler.

Abstract: Measurements of biometric information of a user are obtained over time, such as blood glucose measurements. These biometric measurements are typically obtained by a wearable biometric information monitoring device being worn by the user. These biometric measurements are used by various different systems, such as a computing device of the user or a biometric information monitoring platform that receives biometric measurements from multiple different users. The biometric measurements are used for various security aspects, such as one or more of part of multi-factor authentication of the user, generating security keys (e.g., connection keys, encryption keys), identifying biometric measurements associated with different user identifiers but the same use, and protecting biometric measurements so as to be retrievable only by a recipient associated with an additional computing device, and so forth.
