In some examples, the power supply can supply power to each of the chargeable batteries corresponding with the portable devices via wired connection. For example, the system can include a plurality of first connecting cables and a plurality of second connecting cables electrically connected to corresponding first connecting cables. The first connecting cables can be secured within the first trays and the second connecting cables can be secured within the first trays and the second trays. The power supply can be electrically connected with the second connecting cable to supply power to each of the chargeable batteries corresponding with the portable devices.

The charging method, i.e. wirelessly or wired, can be different between individual portable devices. In some examples, the charging method can be the same for all of the plurality of portable devices.

A charging system, for example charging system1400discussed herein, can maintain the chargeable batteries. The charging system can include a chip or a PCT to control a charge current to the chargeable batteries. In some examples, a fuse can be included to disconnect the chargeable batteries from the power supply when a fuse triggering event occurs. In some examples, each portable device or a combination of portable devices can be disconnected by corresponding one or more fuses. In some examples, one fuse can disconnect all of the plurality of portable devices at the same time.

In at least one example, the system can charge the plurality of portable devices intelligently to improve the lifespan and efficiency of the chargeable batteries. For example, the system can include a neural network to collect data and determine the time, length of charge, amount of power supplied, and other suitable aspects of charging the chargeable batteries. Also, the system can determine charge each portable device according to individual needs and requirements.

The neural network is a multi-layer deep learning network of interconnected nodes. Each node can represent a piece of information. Information associated with the nodes is shared among the different layers and each layer retains information as information is processed. In some cases, the neural network can include a feed-forward network, in which case there are no feedback connections where outputs of the network are fed back into itself. In some cases, the neural network can include a recurrent neural network, which can have loops that allow information to be carried across nodes while reading in input.

Information can be exchanged between nodes through node-to-node interconnections between the various layers. Nodes of the input layer can activate a set of nodes in the first hidden layer. For example, as shown, each of the input nodes of the input layer is connected to each of the nodes of the first hidden layer. The nodes of the hidden layer can transform the information of each input node by applying activation functions to the information. The information derived from the transformation can then be passed to and can activate the nodes of the next hidden layer, which can perform their own designated functions. Example functions include convolutional, up-sampling, data transformation, pooling, and/or any other suitable functions. The output of the hidden layer can then activate nodes of the next hidden layer, and so on. The output of the last hidden layer can activate one or more nodes of the output layer, at which point an output is provided. In some cases, while nodes (e.g., node) in the neural network are shown as having multiple output lines, a node has a single output and all lines shown as being output from a node represent the same output value.

In some cases, each node or interconnection between nodes can have a weight that is a set of parameters derived from the training of the neural network. For example, an interconnection between nodes can represent a piece of information learned about the interconnected nodes. The interconnection can have a numeric weight that can be tuned (e.g., based on a training dataset), allowing the neural network to be adaptive to inputs and able to learn as more data is processed.

The neural network can be pre-trained to process the features from the data in the input layer using the different hidden layers in order to provide the output through the output layer. In an example in which the neural network is used to identify objects in images, the neural network can be trained using training data that includes both images and labels. For instance, training images can be input into the neural network, with each training image having a label indicating the classes of the one or more objects in each image (basically, indicating to the network what the objects are and what features they have).

In some cases, the neural network can adjust the weights of the nodes using a training process called backpropagation. Backpropagation can include a forward pass, a loss function, a backward pass, and a weight update. The forward pass, loss function, backward pass, and parameter update is performed for one training iteration. The process can be repeated for a certain number of iterations for each set of training images until the neural network is trained enough so that the weights of the layers are accurately tuned.

For the example of identifying objects in images, the forward pass can include passing a training image through the neural network. The weights can be initially randomized before the neural network is trained. The image can include, for example, an array of numbers representing the pixels of the image. Each number in the array can include a value from 0 to 255 describing the pixel intensity at that position in the array. In one example, the array can include a 28×28×3 array of numbers with 28 rows and 28 columns of pixels and 3 color components (such as red, green, and blue, or luma and two chroma components, or the like).

For a first training iteration for the neural network, the output can include values that do not give preference to any particular class due to the weights being randomly selected at initialization. For example, if the output is a vector with probabilities that the object includes different classes, the probability value for each of the different classes may be equal or at least very similar (e.g., for ten possible classes, each class may have a probability value of 0.1). With the initial weights, the neural network is unable to determine low level features and thus cannot make an accurate determination of what the classification of the object might be. A loss function can be used to analyze errors in the output. Any suitable loss function definition can be used.

The loss (or error) can be high for the first training images since the actual values will be different than the predicted output. The goal of training is to minimize the amount of loss so that the predicted output is the same as the training label. The neural network can perform a backward pass by determining which inputs (weights) most contributed to the loss of the network, and can adjust the weights so that the loss decreases and is eventually minimized.

A derivative of the loss with respect to the weights can be computed to determine the weights that contributed most to the loss of the network. After the derivative is computed, a weight update can be performed by updating the weights of the filters. For example, the weights can be updated so that they change in the opposite direction of the gradient. A learning rate can be set to any suitable value, with a high learning rate including larger weight updates and a lower value indicating smaller weight updates.

The neural network can include any suitable deep network. One example includes a convolutional neural network (CNN), which includes an input layer and an output layer, with multiple hidden layers between the input and out layers. The hidden layers of a CNN include a series of convolutional, nonlinear, pooling (for downsampling), and fully connected layers. In other examples, the neural network can represent any other deep network other than a CNN, such as an autoencoder, a deep belief nets (DBNs), a Recurrent Neural Networks (RNNs), etc.

Neural network can also be used to perform deep learning. In this example, the neural network includes an input layer, a convolutional hidden layer, a pooling hidden layer, fully connected layers, and output layer. The neural network can identify specific environmental features (e.g., humidity, temperature, amount of charge, number of portable devices, etc.) in an image. First, each feature is considered as a neuron that has learnable weights and biases. Each neuron receives some inputs, performs a dot product and optionally follows it with a non-linearity function. The neural network can also encode certain properties into the architecture by expressing a single differentiable score function from the data on one end to class scores at the other to extract specific environmental features from the target image. After identifying features as specific environmental features, the neural network can generate a mean score (or z-score) of each feature and take the average of the scores within the user-defined buffer.

FIGS.15A-15Billustrate an example of the portion110of the portable device100being secured within a first tray300along with one or more attachments1500. For example, the portion110of the portable device100can include a driver which can be operable to provide power to and manipulate the attachments1500. It should be appreciated that an attachment may be selected from a plurality of attachment types and operable to be inserted into attachment coupling150. The attachments1500may include, but are not limited to, saw blades, wire/pin drivers, and/or drill chucks. The first tray300can include a first compartment331operable to securely receive the portion110of the portable device100. The first tray300can also include a second compartment332operable to securely receive an attachment1500. Accordingly, a kit can be provided that includes all the necessary tools (e.g., driver110and attachments1500) to perform the procedure.

FIGS.15C-15Eillustrate an example of a package1505that is operable to receive one or more than one tray1510,300. A plurality of attachments1500can then be provided within the one package1505or kit. Accordingly, the kit can include all necessary attachments1500and the driver110to perform the procedure.

As illustrated inFIG.15C, the package1505forms a receiving portion1506operable to receive one or more trays300,1510. As illustrated inFIG.15D, an attachment tray1510is disposed within the receiving portion1506of the package1505. The attachment tray1510forms a plurality of compartments1512, each operable to receive an attachment1500. As illustrated inFIG.15D, the attachment tray1510forms three compartments1512such that the attachment tray1510is able to receive three attachments1500. In other examples, the attachment tray1510can form one, two, or more than three compartments1512, to correspond with the number of attachments1500needed or are able to fit within the attachment tray1510.

FIG.15Eillustrates a first tray300being received by the attachment tray1510such that the first tray300is nested within the attachment tray1510which is nested within the package1505. The first tray300, as discussed above, can include a driver110received within a first compartment331. In some examples, as illustrated inFIG.15E, the first tray300can include one or more attachments1500received within a second (or more) compartment(s)332.

WhileFIGS.15C-15Eillustrate the first tray300being received by and nested in the attachment tray1510, in some examples, the attachment tray1510can be received by and nested in the first tray300. Accordingly, the first tray300with the driver110is provided adjacent the bottom (e.g., further from the lid or cover) of the package1505. This configuration can be beneficial as the first tray300with the driver110may be heavier than the attachment tray1510, and it may be easier to charge the driver110in such a configuration.

WhileFIGS.15C-15Eillustrate a two-tiered kit with the attachment tray1510and the first tray300being received in the package1505, in other examples, the kit can be three-tiered, four tiered, or more, depending on the number of attachments1500are needed for the procedure. Accordingly, the kit can provide all the tools needed for the procedure provided in a safe and sterile package.

FIGS.16A-16Cillustrate a tray300operable to receive the driver110of the portable device100. The driver110includes an attachment coupling150operable to couple with one or more attachments. The driver110can also include a handle182for a user to hold the driver110during operation of the driver100. In some examples, the handle182can be disposed at an angle in relation to the attachment coupling150. In some examples, the handle182can be in line with the attachment coupling150. In some examples, as illustrated inFIG.16A, the handle182can include one or more grips180to help the user hold onto the handle182.

The driver110also includes a trigger160. Trigger160may be provided to vary the speed of rotation of the interior of attachment coupling150. It should be appreciated that trigger160may be provided to control the direction of rotation of the interior of attachment coupling150in a clockwise direction or in a counterclockwise direction without departing from the present disclosure. It should be appreciated that the driver110may provide a variable-speed trigger160and/or an instant-reverse trigger160in some embodiments of the present disclosure. As illustrated inFIGS.16A-16C, the trigger160can extend from the handle182. The trigger160can include an arm164extending from a surface184of the handle182, and a finger rest162coupled to the arm164. The trigger160can be actuated by enacting a force against the finger rest162so that the finger rest162moves towards the surface184of the handle182. When the trigger160is actuated, the power supply of the driver110is activated to power the motor.

To prevent compression of the trigger160, the tray300forms a trigger guard334. In at least one example, the trigger guard334can be integrated with the tray300as one piece of material. In some examples, the trigger guard334can be coupled with the tray300, for example by adhesive. The trigger guard334projects from and/or extends from the tray330such that the trigger guard334is disposed between the finger rest162and the surface184of the handle182. In some examples, the trigger guard334can receive the arm164of the trigger160and abut against the inside of the finger rest162and abut against the surface184of the handle182. Accordingly, if a force is enacted on the trigger160when the driver110is correctly received in the tray300, the trigger guard334prevents the finger rest162from moving towards the surface184of the handle182. In other words, the trigger guard334prevents compression of the trigger160. Accordingly, the battery cannot be engaged while stored in the tray300. This improves safety and sterility of the driver110while stored within the tray300.

Any of the features discussed and illustrated inFIGS.15A-16Ccan be implemented along with any of the features discussed and illustrated inFIGS.1-14.

It should be appreciated that embodiments of the present disclosure may provide for usage in conflict zones or natural disasters, where charging equipment may not be possible. Further, usage may be provided in geographic locations that may not have access to an adequate power supply and/or sterile environment cannot fully charge medical equipment and instruments. However, usage in hospitals and other medical facilities may be improved insofar as devices containing tools necessary for medical procedures may be readily available off-the-shelf and for immediate use at a cost that has significant advantages over other reusable tool systems.
