Abstract: A server device can obtain historical location data, concerning a vehicle, captured by a global positioning system (GPS) device of the vehicle and historical engine control unit (ECU) data concerning the vehicle captured by an ECU of the vehicle. The server device can process the historical location data and the historical ECU data to train a machine learning model to determine a relationship between the historical location data and the historical ECU data. The server device can receive location data and ECU data concerning the vehicle and update the machine learning model based on the location data and the ECU data. The server device can receive real-time location data concerning the vehicle and derive an equivalent real-time ECU speed using the machine learning model. The server device can generate a message regarding the equivalent real-time ECU speed of the vehicle and send the message to a remote device for display.

Abstract: A floatation accessory for a pool vacuum is an apparatus that maintains an inverted position for a pool vacuum such that the mouth of the pool vacuum suctions debris along the surface of a pool. The apparatus includes a support platform, a first float, a second float, a support ridge, a handle, an elongated guard, and a suspension system. The support platform upholds the first float and the second float. The first float and the second float are used to float a pool vacuum that is engaged with the apparatus. The support ridge connects the first float and the second float and offsets the elongated guard from the mouth of a pool vacuum. The elongated guard offsets the mouth of a pool vacuum from the side walls of a pool. The suspension system loops a pool vacuum with the support platform, and consequently the first float and the second float.
