Okay, sorry.
Lets elaborate on what you can do with focus mitts.
Please let me know if this is what you were looking for.
First of all, what level of training are you at?
Do you have your gaurd down? Can you defend while attacking?
Do you have your footwork down?
Do you have your jab and cross down?
Do you have hooks down?
Do you have elbows and knees down?
The first thing you want to do is get a rhythm with your partner.
Whoever is striking needs to focus on a few things AT ALL TIMES and during ALL DRILLS:
Never stop moving: always keep your foot work going. Always work. Bob/weave, move backwards forwards and sideways while keeping your footwork and your gaurd.
Strike Controllably: You never want to allow yourself to strike wildly or without concern of your gaurd/footwork. If you drill controllably, and work HARD to keep control while fatiqued, during a fight you'll be able to defend yourself better and for a longer period of time.
Strategize: This may be hard to do when you are facing mitts, but at least try to visualize certain combos mixed with footwork and defense, and get them natural, so as to keep an arsenal that you can use for different opponents. Just as you want to keep your body working, keep your mind working.
Specific Drills
I would drill for at least 3 minute rounds, with a couple sets.
1,2 / 1,2,3 / 1,1,2,3,3 etc. etc. : 1 = jab , 2 = cross , 3 = lead hook
This will be the first drill you use on the mitts. Start with simple 1,2's until both you and your partner are comfortable.
Once you are ready to move on, start to change it up.
Your partner calls out certain combos and you attack the mitts accordingly. You can make up your own numbers or whatever, and definately change the combos up. This is good to get yourself versatile and able to throw anythiing that comes to mind. It is also the first step to getting conditioned on the mitts.
Accuracy/Technique Drills : Save this for after you are conditioned. Choose a specific strike and focus on it solely for the drill period. Your partner needs to know how to hold the mitts properly for each strike, or you wont learn properly.
Strike-Outs : This is for increasing stamina. Throw a barrage of 1 & 2 's without rest for a specific amount of time. A good drills is 15 seconds on, 45 secs movement and gaurd, about 10 times. This should kill you. You can variate this though.
You can also throw other strikes like this (i like to use hooks). It helps co-ordinate multiple strikes.
Power Drills : This is where you choose a specific strike and throw it HARD. As hard as you can. You must make sure to keep your gaurd, footwork, and striking form solid when doing these, otherwise you are wasting your time. Power starts with form.
You can use other strikes to set up whatever strike you are working on, just keep them light. You want energy for the specific strike you are working on.

Dont forget the bag drills either. Read the stick by King Kabuki, and if you Thai box, throw in a round for knees/elbows and a round for kicks. And eventually a round for all strikes in your aresenal.
